CS4 a load of pants?

CS4 is to flash what Vista is to Windows. Slow, unstable and unpredicable.
I had switched to coding in Notepad++ and more recently I have discovered FlashDevelop3 which is a tremendus improvement.
What does everyone else do? Its there a patch I can use to make the flash IDE just work like a normal editor? I have 4GB ram and a very fast laptop, so it cant be that.
