Hi, thanks for answer.

Yes I can duplicate this error at will. Only if I send a message, without POP3 check/download during the shut down or uncompleted sending process.

I just find out that I made a driver update for my Wacom Tablet (Intuos) today. With the tablet usb connected, I have this error (runtime error 216). Without the tablet connected, no problems.

Hello

When I close Pegasus Mail after I sent an email, here is the window that opens: Error : Runtime Error 216 at 06D24E7E.

Another time: Error : Runtime Error 216 at 074C4E7E

I'm using Pegasus Mail  4.72.572, with Windows 10 Family x64

Thank You

Luc

There are a number of discussions about this error that a search will point to.  The most recent one is here:

A common occurrence between two posters to this thread was the upgrade by Win10 to the 1607 Anniversary edition.  There was no solution posted though.

Other discussions have identified this error happening when Pegasus Mail is shut down while it is doing a POP3 check/download.  Might happen on send too if the send process wasn't complete.

Can you duplicate the error at will?

Did the problem just start?  If so, what changed with the system?
