I guess I'll add to the so far unanswered questions... In IE8 when opening a pdf file, sometimes, my browser will freeze. I've done the uninstall-reinstall a couple times which has not changed anything, and based on all of the other similar inquiries and feedback, this sounds like more of an Adobe problem than a browser problem. I never had this issue with my earlier versions of Reader. Does anyone have the tried and proven fix yet???
No words of wisdom? This is a problem that occurs only when trying to open an Adobe pdf file and only happens once in a while and requires me to close out IE. Re-opening IE will then allow me to open the pdf file. Since I typically will have 3-5 browser windows open this is a hassle to relaunch my pages and online apps.
