Same as above, the problem occurs as soon as I press "test" and end the test.
What I did was simply open any VS, press test, end test, and no dialog box opens. The program just flashes. If I try to close the program a pop up shows up asking if I want to "Save", "Do not save", or "Cancel". If I press "Save", the program flashes and does not save.
If you lose a theme this way go into %temp% switch to details view (if it's not already) and grab the latest ave****.tmp
