qnx has been touted as so robust it runs routers, nuclear power plants, etc. but the performance really has not lived up to the hype so far. I can't imagine how apps just keep freezing after they are left unused for a while particularly after standby. Just about every app i use daily freezes - browser, pdf reader, facebook, etc. Hopefully .2390 fixes it. And they really should tell us upfront what an update includes.
