Update! I just received the new icebgset 1.1 and everything works perfectly now! This is great news, as I've spent the better part of the last 6 months, (with MUCH googling and NO help from anyone!), trying to configure pygtk in the way that icepref/IceWMCP wants it to be to work! God what a nightmare THAT has been! BUT...no longer...
Anyway, there had been an issue with icebgset in releases 1.0 and earlier that caused it to "freeze up" when trying to install a background. This was iritating in that you had to either Ctrl-Alt-Backspace out of it, or Xkill it, and the background you were trying to use would not stay put when re-logging in to IceWM.
As of today, 10/24/03, the newest release of icebgset, created by Vadim A. Khohlov, works PERFECTLY!
Not only is there no longer a freeze-up, but the background image you choose will be there again when you re-login!
With this new bug-fix, Icecc is now your complete and dependable all-in-one configurator for EVERYTHING in IceWM with ease!
