Rainlendar2 goes black in Ubuntu
I am using Ubuntu 10:10 (maverick), Kernel 2.6.35-17. I just did an update. AFter this when I went to log in I could not get the gnome display. Not sure how I fixed that (real trial and error) but now I can be inside. When I open one of my programs now "Rainlendar2" a calendar program that has always worked without problem, all I get now is a black box shaped liked the program. I can't see anything.
I have posted this question in ubuntu forums and also rainlendar2 forums but no advice is forthcoming so far. I've uninstalled and reinstalled rainlendar2 but still this problem remains. Nothing else seems to suffer from this upgrade (as far as I can tell). I'm hoping someone might be able to direct me, show me, help me figure out how to solve this. I'm still relatively a Linux novice. I include a screenshot.
Thank you in advance.
