Unstable VST support in latest BETA 25.3.0 build 27

VSTs on audio track used to work fine across previous BETA 25 releases, but 25.3.0 crashes all the time when I edit VST parameters. I also get frequent audio errors in the yellow box, telling it can't find audio. Replaying the same section then works. So far, 25.1 BETA has been the most stable.  

ALSO, the overwrite warning of all Adobe products that save a file do not check the extension. This bug has been nagging me for YEARS and applies to all products that use common dialogs in Windows. 

When you save an IMAGEX with a default .PNG extension, it wil overwrite an existing IMAGEX.PNG with no warning. When you save IMAGEX.PNG with the extension in the filename, it warns. Please fix this because I've overwritten way too many files when I shouldn't.

Cheers,

Robert.
