Typing lag in Vista Ultimate with CS5+, Not XP SP2

I just upgraded my PC to Vista Ultimate SP2 again and the typing lag in class files in Flash CS5.5 and CS6 is hellish… In a file beyond two pages it’s ridiculous!

I just remembered why I downgraded to windows XP SP2 a year ago… LoL!

This glitch ever going to get fixed?

I am about to find another editor to code my AS3 in… The auto-completion in the flash IDE is so nice though…
