Well, I've got a problem.
Linphone 3.6.0 works fine, excepting the enable self-view button, provided putting up with a 30 minute load time is "working fine."
And lyx 2.0.6 works fine if started from the command line but not if started from the gui. For example, if started from the gui, Lyx crashes on "save file," but saves fine if started from the command line.
And some other programs are looking different. For example, etm (started from the command line with etm_qt.py) works and looks fine, but etm started from the gui seems to work fine but has bigger and bolder font.
My attempts to fix by a vasm autosetup, reloading qt4, and reloading python and wxpython did not help.
Any suggestions? I obviously have screwed up something pretty basic to the vector linux system.
