Back in November of last year I vented about how often Flash CS4 crashed. The blog post became fairly popular and still seems to be one of my top 5 posts read each month.
Back in May, Adobe released an update to Flash CS4 which Galvan discusses the specifics here. Ever since I downloaded that update, running Flash CS4 has been extremely smooth. I no longer have the crashes that I had before. I no longer save every time before I compile (although that one will probably bite me at some point). I am not going to say it hasn't crashed since that update... but I will say that I can't remember the last time it did crash. I know I just jinxed myself hard core, but it needed to be said.
Flash CS4 != Crash. The doors are open for those of you who ran away and the light is green for those of you who waited for a safe build.
And no, I am not being paid by Adobe. Although donations from Adobe would be accepted ;)
