Why after so many years is there still an intermittent issue with pressing spacebar to preview. If i restart AE is goes back to expected fucntionality. I've got no special settings. No caching issue. No low ram etc etc.
I've had this problem throughout the past 10 years with AE. Multiple rigs, multiple versions of AE - it's the single thing that's been consistent.
Some one give me an answer or tell me it's a known bug in the software that's for some reason impossible to fix.
What bug? What issues? Juist posting generic "This sucks!" posts is not useful to anyone without proper technical info. And it seems that despite your claim of using AE for ten yoears you do not understand the limitations of this feature, how it came about, when it may simply be more adequate to use traditional RAM previews, how hardware accelerated functions relate to it. You may simply have to accept it. Anything else will require proper technical information.
