This problem has been occuring for a long time. I'm using Flash CS5 Pro on Windows 7 64bit. When drawing, the CPU usage of Flash bumps up to 100% causing music playing in Chrome to pause, or music playing in itunes to stutter. 8GB RAM, 2.8ghz Duo Core.
Everytime I try to find a solution, results come up for the Flash player, so this has been pretty frustrating. This happens in photoshop CS5 aswell. Please assist, thanks !
Try finding another resource for playing your background music.
ah weird, trying it again now and there's no stutter and drawing doesn't spike the CPU. im using a soundcard so i've been playing music off a different resource. i'll have to wait until it happens again and switch the sound device to see if it was hardware related. it seems like it's some sort of memory leak type thing but for the processor...hmm i dunno
