Just to report that I did a fresh install of PMail on my desktop machine, as a result of which (touch wood!), drag & drop works fine for attachments, and other problems have been cleared up, such as a corrupted Junk mail folder and inability to use PMDebug and get my video card to load PMail on my 2nd monitor.  So that's good.  Hope it lasts.

I then copied the whole PMail folder to my laptop, but sadly the drag & drop problem persists on that machine. (Note that I don't get the "No entry" cursor:  the cursor looks exactly as it should for a copy operation.  It's just that the dropped file fails to appear in the attachment pane.)  Perhaps one day I'll make time to do a proper fresh install of PMail on my laptop too, but this has taken enough time already.  Thanks to Martin and Brian above for their time.

Sorry to have to return to this problem (http://community.pmail.com/forums/thread/37274.aspx).

For some time the installation on my laptop hasn't allowed me to drag and drop an attachment into the attachment window.  I have

to click Add attachment and go through menus.  The option for multiple

attachments is enabled.  My home desktop machine was fine.  (Same PMail, 4.6.3, very similar flavours of Win 7 x64.)  Now my home desktop is showing the same behaviour.  Nothing has been copied from laptop to desktop as far as I recall.  Both machines get the standard Windows patches and updates.  Within PMail I may have updated bearhtml, mapipm.dll, LibTidy.dll, IERenderer.  Can anyone suggest where I should look to see why drag & drop has stopped working?  Thanks.

I can drag & Drop from Windows Explorer into the attachments dialog without problem.  The cursor changes to the rectangle with Plus sign until the attachment is released on the attachments page (anywhere). It sounds like you have a problem mouse that is not signalling Keydown continually, until you release it.

But that's just it:  so could I (drag & drop attachments) on both machines - have been doing it for years, with the same equipment.  But then first my laptop (many months ago) and more recently my desktop (maybe last week) stopped allowing it.  I get exactly the cursor you describe, but when I release the left mouse button, no file appears in the attachment window.  These are very different mice:  on the laptop, a TeckNet wireless mouse, on the desktop a Dell wired mouse.  And other drag & drop operations in Windows work fine on both machines.  That's why I'm so baffled:  what could have changed in the Windows/Pegasus interaction?

I appreciate your contribution, Martin.  Does what I've written change anything or suggest any other avenue?,

Could you try a drag and drop on a message in a folder, and drop it into your NewMail directory. That would test the basic Drag 'n Drop mechanism. If that works then it would have to be the Windows Explorer interface and Pegasus Mail, which then seems more likely to be a Mouse driver problem. watch the cursor shape during these tests to see if/when the shape reverts to standard pointer.

I am suspicious of the recent flurry of MS fixes to the "system".  I am fully up-to-date on my XP system, but I cannot as yet duplicate your problem.

Martin 

I can't duplicate it at the office either (3 different instances of PMail running on XP).  I will test on my Win7 64bit laptop at home tonight.

Martin:

Just tried dragging & dropping a message (a) from one IMAP folder to another IMAP folder, (b) from an IMAP folder to my (local) New mail folder, (c) and back again.  All worked fine. Is that what you meant?

What I couldn't do is drag and drop text from a text editor window or from MS Word into the PMail edit window - but I have no idea whether that would normally be possible anyway.

As for dragging a file to the attachment window, the pointer stays as I think it should (normal pointer with dotted rectangle and additional rectangle with plus sign) until the moment of release over the attachment pane - but the file doesn't then appear.

Brian:

Just seen your message.  Thank you too for your trouble.  Just wanted to say that this used to work fine on both my Win 7 x64 machines, and now it works on neither of them.

Maybe the link below tells you something:

http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/drag-and-drop-not-working-in-windows-7/f6dcfa11-8c51-e011-8dfc-68b599b31bf5

Notice the solution to re-enable Drag And Drop :-))

Wow.  That long thread is full of people with drag & drop problems and bizarre solutions.  Some people find a given solution works, some don't:  (a) press Esc when dragging a file (didn't help me);  (b) run both programs - the drag-from and the drag-to - as Administrator (didn't help me);  (c) press Ctrl-Alt-Del and then Esc.   Now that last fix just starts Task manager and cancels it, but it has - at least for now - fixed drag and drop to PMail on my desktop machine!  That is weird.  However, it didn't fix the problem on my laptop.

When I have time I'll work through that long thread to the end and report back if I can make any sense of what's going on.  Meanwhile, Martin, I'm most grateful for the tip.  Thanks.
