--- Comment #18 from mbeller...@ypsilon.net --- 50 days have past on my machine. $ uptime 10:54:38 up 50 days, 4 min Alt-Tab is still working. I can move and resize windows around. Nice. But copying from old windows is still broken. When I copy (mouse select, mouse select - right click - copy, select Ctrl-C) in KDE/Qt-Windows, nothing is copied. No new entry in klipper. And something different then the copied thing when I paste somewhere (Ctrl-V, mouse middle click, mouse right click - paste). It seems specific to those KDE/Qt-Windows, because copying from Firefox, XTerm, GVim still works. And pasting in old KDE/Qt-Windows works too. When I restart the application, it works normally again.
