Google Toolbar 3.0 for Firefox: bug!

That's been driving me mad all day today. I have tried everything, from uninstalling Firefox, reinitializing the toolbars and buttons, even reallocating the bloody pagefile , no result!I've even thought that it could be Vista... The issue I'm talking about is getting an extremely choppy scrolling in Firefox windows as soon as the mouse cursor passes over links. A couple of minutes ago I disabled the Google toolbar, which I normally find very useful. AND HERE WE ARE: THE BUG IS GONE!
Don't worry I won't leave it there, I need that toolbar, will re-enable it, and troubleshoot it until I find what in it brings that extremely upsetting choppy scrolling of web pages in Firefox. More as it comes...

updating:It sounds like this Google Toolbar Version 3.0.20070201W, even when remaining as the only enabled extension in Firefox, brings the bug. It's a no go.
