I probably should have clarified the problem .....What I did was accidently re-size a window in the program. The program still runs, but it displays one of the program windows full screen without any way to minimize or close or do anything! I havent tried the suggestions posted yet cause I was working on another project over weekend, but tonite i will go back to this problem. Maybe when i turn on computer k3b will be back to normal. The problem i was having is trying to figure out how to burn an .iso file to cd. I have been using a WINDOWS program to burn .iso's but I want to be able to use k3b. I couldnt find any reference to burning .iso files on any menu or any box to check for that function....I will post back later tonite...bob
