What a day!

Had to uninstall and reinstall FF4 about three times, do a system restore twice, then found out that for some crazy, heretofore never experienced reason, NoScript was screwing with my browser. Finally managed to clean the system and reinstall both FF4 and NoScript...one annoying problem remains, though. While the NoScript icon now *does* appear (it was gone for a long time and add-ons would freeze the browser, don't ask!!), it does not open either to left or right click. I do get "options" when I first log on to a site and can enable java etc...however, once the site is running, the icon seems to be dead. I would not be able to de-activate java or other components.
I have been at this since 6am and it's now 2pm (yep, no life!) Things are at least running now which is great but I'd like to get to the nub of this last problem. Btw, I have completely cleared all history, cache and all personalization and previously installed toolbars and extensions to even be able to get to where I am
Thanks for your help
