When I try to drag a message from the message list into a folder in the folder tree or the preferred folders list, nothing happens except some short flickering. (No menu popup, no message is copied or moved.) This may be related to bug 290869, since the mouse pointer is also not really behaving consistently (there is no visual feedback of the dragging, and occasionally while moving the mouse the "No drag target" symbol flickers, but on the whole the pointer remains the plain hand). Gentoo kde-4.7.95, with qt-4.7.4; will test .97 shortly.
No change in kde-4.7.97, dragging of messages still broken
OK, to describe this a bit more: Start situation is, I have kontact open on the kmail page, with folder tree, message list of one folder and one e-mail displayed. I want to pull one message from the message list into one of the folders displayed on the folder tree. kde-4.7.97, kdepim-4.7.97, qt-4.7.4 (office desktop) 0) Mouse pointer is arrow. 1) Press mouse button down on message entry. 2) Start dragging. The mouse pointer changes to a hand (NOT displaying a "no valid target" or "dragging message" indicator). 3) When I move the mouse pointer rapidly I sometimes see the "no valid target" indicator flickering up. As soon as I stop moving the mouse, I only have a hand again. 4) I move the mouse pointer on top of the target folder. 5) I release the mouse button. For a short moment, a context-menu-like widget flickers up with a message similar to "Getting mime info", don't remember exactly 6) That's it, nothing else happens. Mail stays as it is. Interestingly, on my home desktop running kmail*1*, I very recently also see problems- so the bug may not be in kmail directly, but may e.g. have been introduced somewhere between libkdepim/kdelibs 4.7.85 and 97. Symptoms are slightly different: kde-4.7.97, **kdepim-4.4.11.1**, qt-4.7.4 (office desktop) 0) Mouse pointer is arrow. 1) Press mouse button down on message entry. 2) Start dragging. The mouse pointer changes to "dragging mode, no valid target" 3a) 80% of attempts: When I move the mouse pointer rapidly I sometimes see "valid drag target" flickering up, but the highlighted drag target is not exactly below the mouse pointer! As soon as I stop moving the mouse, I only have a "dragging mode, no valid target" pointer again and cannot drop anywhere. 3b) 20% of attempts: drag and drop works fine
I noticed this a couple of times on 4.7.95. I rarely move emails between folders, so those were the only times I tried. I don't remember noticing any flickering or the mouse pointer issue. I have just tried it on 4.7.97 and it works again for me. All my kdepim packages are at 4.7.97 and I'm using akonadi 1.6.2 and qt 4.8 on Arch Linux.
