Any VFX applied to timeline does not immediately show. Any change to the parameters in the effects editor also does not show up till you close the effects editor window. Split screen button not enabled. Vegas Pro 15 running on Win 10. It was working well earlier. Please help
I read through all the links provided by vkmast, tried and wow it works! Thanks a lot. You guys are awesome. Dear Cornico, you may not research further, thanks for your efforts.
