Ok, I just did that and it is still doing it :(

I tried to delete the "Simon" figure from the scene and the "Are you sure you want to delete the current figure?" window is 'stuck' on the screen.
I have tried going to the tool bar and clicking delete figure from there, and just hitting delete on the keyboard.. and both ways that window stays stuck on the screen and I'm forced to have to go to the Task Manager to shut the program down.
I want to avoid a complete system restore, but if I have to I will.
