Version: (using KDE KDE 3.4.3)
Installed from: Ubuntu Packages
Is this an AmaroK bug or KDE Windowing system bug?
I reported this earlier as AmaroK bug 127836, which was marked "INVALID", as they judged this to be "a window manager issue, afaict".
With window focus setting set to "Focus Follows Mouse", AmaroK window does not gain focus when files are dragged and dropped to it.
When you further move mouse on AmaroK, it still doesn't get focus. Only when you move your mouse away from the AmaroK window and then back does the player gain focus.
PS. The annoying thing - you drag and drop from somewhere in your file system (or from desktop), and then press Del to remove e.g. the currently playing song in AmaroK, only to find out that the "Del" keypress was relayed to the desktop, and those files are then deleted / "moved to trash", with / without confirmation asked, according to what settings you have.
This issue is somewhat parallel to the one described in bug 142040, showing similar symptoms.
