When you insert an effect -for example brightness- Video Event FX opens then you alter with the options and while you're doing it you see the changes on the preview screen am i right? But for some reason its not happening on my Vegas.
In other words i cant alter with the options and see what the option changes at the same time, i have to close the Video Efent FX window and the effect applies after that. It may seem unimportant but its a HUGE deal to me.
I didn't have this problem when i was editing on my old computer but when i started editing with my new computer this problem occured. So maybe there is an option that i don't know or something?
