Other CS4 BUG.
BUG APPEARS: when you trying to optimize bitmap in library (changing JPG compression level).
BUG RESULT: Errorous bitmap (disappearing , flickering, blinking,…) in final SWF file or in flash preview.
SOLUTION: Save (with optimized jpg), Close (FLA with bug), Re-Open FLA, Re-publish. Result must be OK.
If you see the same problem with other JPG try again (each time this bug appears do the same operations).
This bug is old bug of cs4 (Windows XP SP3). Problem is important for banner makers.
Problem:
When flash CS4 isn’t loaded yet.
It’s impossible to open several selected FLA files - flash crashes on starting point

Nothing changed from initial CS4 release. I am using original product (not hacked/cracked), but result is the same after several updates from Adobe.
Before opening several files you must start Flash CS4. Then select several FLA files and press enter.
I DISSAPOINTED about adobe software quality. Too much bugs and too much unimportant features.
If you are newbie – don’t forget!
