Hi daxb!
When I start the rndwbpix program, it does not seem to work, even when I put it to change the wallpaper every 3/10/15/60 seconds!
The RandomBG program seems to have started to work again, but before that it did not seem to work either.
I start one of the two always one line before the "C:IPrefs". I tried to start them inside AmigaShell in the Workbench, as you said, and only RandomBG worked.
Hmm, I need to get more wallpapers for my Workbench, because that "might" be what's causing the problem...
Thank you for your attention!
