Well I was going by your comment of "I was messing around with fullscreen shaders in Beta 7 and they worked fine, but when I upgraded to Beta 8, they stopping working". That is why if it relates/involves the BETA(s) of FPSC, it is better to post the questions/issues there. That is what the thread is for, no matter how miniscule the question is. Besides, someone else may have a similar issue and may have an answer or find the answer in that thread.

There's no problem that can't be solved without applying a little scripting.
