Thanks for the response so quickly. Windows XP. Yes, I used the repair also.
The freeze occurs when I chose the paint bucket tool and moved it to a .jpg project in order to change a background color. The tools bar "went blank," no paint bucket "action" occurred at that point, and the program froze. When I tried to close the program, no luck. It would not close. So I had to do a restart on my computer. This scenario happened once before the repair option and twice after I used the repair option.
Do you think I should remove the new version of paint.net and then re-install it fresh? Thank you so much.
