With a little help of a friend and some clues from various sites, I've finally solved the problem.
In fact it is not a perl-tk bug (as I guessed), but a problem with xorg in combination with a weird behavior of Tk. Before the problem was solved, starting wish failed with that error message: [EMAIL PROTECTED] ~ $ wish; echo Application initialization failed: this isn't a Tk applicationunknown color name "Black" % [EMAIL PROTECTED] ~ $ At last I checked my xorg log file and there were these lines: (**) RgbPath set to "/usr/lib/X11/rgb" (**) ModulePath set to "/usr/X11R6/lib/modules,/usr/lib/xorg/modules" (**) Option "AllowMouseOpenFail" "true" Couldn't open RGB_DB '/usr/lib/X11/rgb' So a simple symlink solved the problem. --Michael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
