I'm running SmarterMail Enterprise Build 9091 on Ubuntu Server 24.04.1 and Firefox 133.0 (64-bit) on Windows 11 Pro 24H2.
In the web interface as the primary system administrator, in:
Manage -> Message Archive Search -> Search for and select a message -> 3 dots button -> Copy To Mailbox (or Copy All, without selecting a message)
There's a minor display issue with the Folder drop down box. When I click certain folders, the Folder field doesn't update to display the folder I just clicked, but the Destination Folder field at the bottom does update correctly.
This problem only happens for some folders, apparently the ones that are the "default" ones (Deleted Items, Drafts, Inbox, Junk Email, and Sent Items). When I click one of those folders, the folder that was previously selected remains in the field (or just "Folder" if no other folder was clicked first).
If I click Copy, the message(s) does get copied to the correct place (to the folder shown under Destination Folder), so this appears to be simply a display issue in that dialog.
In this screenshot, I have selected a folder I created manually called "Archive", which works correctly.
Then, I clicked Inbox in the Folder drop down box. Notice that even though Destination Folder correctly shows Inbox, Folder still shows Archive, which is what was selected before.
