if anyone has upgraded to IE7 and has the Google toolbar installed, just bear in mind that this can cause hassles... I kept on getting error messages ("IE has encountered a problem and has to shut down, we apologise for any inconvenience") - I would then debug ONLY, or the whole darn thing would shut down! (ie if you reported the error, it would tend to shut down, no fun when working with a lot of open windows)
Sooooo, the microsoft ppl think they have isolated the problem as they helped me uninstall the toolbar, then reinstall the bar. Problem seems cleared up, app. caused by the upgrade to IE7!!
Just thought someone might want to know this :-
