I'm having a little problem my project file is jumping from 12mb to over 200mb when making small changes to anything in the file?

Adobe knows of the problem and it will be fixed in the next update. The work around now is to keep deleting your preview files. Make sure you do this soon because if it gets to big it wont open anymore.

Ah thank good for autosave files!! I've only made a small change so wont make much different for me to revert back.

Deleting preview files will be a pain in the backside, just for that project or all projects?

Thats mad! 12mb project to over 200mb. Revert back to the 12mb project delete preview files and save again and now the project is 4mb!!

I've deleting my preview files every other day. Hope for the fix soon.
