View Source stops working when running multiple instances in FF4

I run two instances of FF each under its own profile. I have different add-on, etc, for each.

Since upgrading to FF4, View Source is not working in the second instance. After pressing Command-U or otherwise choosing View Source, nothing happens. If I go to the "Window" menu, I see a window listed "Source of ..." but this window is not visible in any way and I can't find it or switch to it.

Seems to work ok for me but I am using windows XP. I have firefox 3.6 & 4.0 both open, and both have now opened view source windows. Possibly some combination of extensions causes the problem.

In my case I am running two instances of 4.0. I'll give it a try with extensions disabled.

I managed to get it working again by using the "reset toolbars" option in the safe mode startup. I haven't figured out the root cause but this at least fixes it.
