Version: (using KDE KDE 3.5.5) Installed from: Ubuntu Packages OS: Linux With enabled Active Desktop Borders (Always enabled, 100 msec delay), dragging something, e.g. an icon from the desktop, to another virtual desktop behaves strange. When I move the cursor to the desktop border, nothing happens. I have to continue moving the mouse to the direction of the border, even though the cursor is already there, to make the virtual desktops switch. Because I have to continue to move the mouse, these movements are continued after the desktop switch, possibly leading to multiple desktops switches. This makes controlling desktop switches when dragging something nearly impossible. Dragging windows works fine. Switching desktops without dragging anything as well. Example: You need 3 desktops for this, all arranged horizontally in the same row. Go to desktop 1, grab any icon of the desktop and try dragging it to the right desktop neighbor, desktop 2. You'll notice that you have to continue moving your mouse to the right to make it switch happen eventually. After that, the cursor immediately jumps to the rightmost position of desktop 2, leading to a possible unwanted switch to desktop 3. I hope I could make myself clear.
The bug is a bit different on KDE4: dragging an icon never trigger the change desktop moving the cursor on any edge of the screen.

Sidenote, i figured (while trying to avoid dolphin crashing when withdrawing the input window) that gtk+ applications do NOT grab the mouse on drag and drop (ie. grabbing it is likely what causes the Qt issues)
