Hello, these are surely related: after reading the changelog.Debian.gz for Qt and the behaviour I observed it became apparent. I fixed it for myself the Quick and Dirty way: replaced /usr/lib/qt2/lib/libqt.so.2.2.2 with the version from libqt2.2_2%3a2.2.2-0.potato.1_i386.deb and Alt-F2 did not switch desktops anymore. Bart
