Does anyone have problems with Adobe Flash CS3 crashing on them?

Such as when opening the actions panel or doing other various functions...

What operating system are you using? What are the specs on your computer?

I'm using windows xp on a 2.40 GHz processor with 768 RAM.

Also, it only seems to happen when I use actionscript 3.0. Since I have been using actionscript 2.0 lately, I have not seen any crashing.

768 mb*

seems your PC supports the needed requirements:

    *  Intel® Pentium® 4, Intel Centrino®, Intel Xeon®, or Intel Coreâ„¢ Duo (or compatible) processor
    * Microsoft® Windows® XP with Service Pack 2 or Windows Vistaâ„¢ Home Premium, Business, Ultimate, or Enterprise (certified for 32-bit editions)
    * 512MB of RAM (1GB recommended)
    * 2.5GB of available hard-disk space (additional free space required during installation)
    * 1,024x768 monitor resolution with 16-bit video card
    * DVD-ROM drive
    * QuickTime 7.1.2 software required for multimedia features
    * Internet or phone connection required for product activation
    * Broadband Internet connection required for Adobe Stock Photos* and other services

    * 1GHz PowerPC® G4 or G5 or multicore Intel® processor
    * Mac OS X v10.4.8â€"10.5 (Leopard)
    * 512MB of RAM (1GB recommended)
    * 2.5GB of available hard-disk space (additional free space required during installation)
    * 1,024x768 monitor resolution with 16-bit video card
    * DVD-ROM drive

heh... My FLA self destructed and so I went to import my 618 kb game and POOF! Flash Crash (hey, thats catchy!)

well then perhaps it is something to do with using actionscript 3.0

i have vista and when i try to run flash MX 2004 or earlier it crashes, but flash CS3 is totally fine, maybe your problem is just like this, only backwards... program compatibility issues and all that, since your computer was made much earlier than any version of flash that supports actionscript 3.0, it could be that you just need to stick with actionscript 2.0 untill you get a new PC!

...I was using AS2.0... this is also in a class i take so the computers are extremely fast
