Version:           0.60.82 (using 4.1.96 (KDE 4.1.96 (KDE 4.2 RC1)) "release 77.1", KDE:KDE4:Factory:Desktop / openSUSE_11.1)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.27.7-9-default

When Kopete is set to show a message window on incoming messages (default behavior) nothing happens when I click the "View" or "Ignore" button on the window when I receive a new message. Normally, View would close the notification window and show the IM window but neither happens.
The only way to close the notification window is to drag it. If I drag it a bit away from it's default position in the bottom lower right corner it disappears when I release the mouse button.

This is consistent behavior. The buttons *never* work for me.
