Greetings all -

Recently upgraded from 4.7 (as I recall) to 4.80.1028. I have always from early years using PMail sorted my mail into filing trays and folders. Until now I've been able to double left click a mail folder to open and view its contents while also being able to double click an individual email message to view and reply to it as well. While I can still open the individual messages, double clicking a folder fails to open it. I can open it with the 'Open' option on the menu bar above the folder window so it's not a big problem, just something that I always found convenient to readily access my mail folder contents. I did figure out I had to upgrade the IE Render app on my PC since once clicked on a folder name, PMail would essentially freeze for some reason but I go that sorted. Is there something I've overlooked in the setup for the new 4.8+ PMail version that will enable double click opening of folders?

Thank you very much in advance

I haven't seen any other reports of the behavior and, AFAIK, nothing changed in v4.80 that should have caused it. A restart of Pegasus Mail is my first suggestion. A cold boot of the PC is my second. Finally, test with a different mouse if you have one.

If you're using Pegasus Mail in preview mode and maybe on a slow machine it might get caused by the rendering of HTML messages for preview not being finished when encountering the second one of the clicks - if the first message in the folder to open actually contains HTML. It's due to the fact that HTML rendering takes significantly more time than displaying plain text even without loading embedded pictures and that IER needs to disable all user input during rendering since it would otherwise possibly cause crashes (a very long standing issue with preview mode, actually one of the hardest to fix issues ever also affecting navigation through folders - aside from IMAP ;-)). You can check this by cross checking: Switch to non-preview mode and try again, your double click should now work to open folders since rendering HTML message isn't involved anymore. Same effect if the folder's top message only contains plain text: The folder will open as you expect to on double click.

PS on 2023/01/04: The same applies to double-clicking messages in preview mode, see this post.
