Hi, I'm using FF 1.5.0.2 on Win2k SP 3 and occasionally, with no
trigger I have yet discovered, FF displays these symptoms:

* cannot click on a link
* cannot click on a different tab
* cannot click in the URL field
* cannot click on a link in the Links bar
* cannot click on Reload Page or Back, or any other highlighted icons

* CAN close a tab, but the same symptoms occur on the next tab under
* CAN close the window using the X in the top right
* CAN move window focus from & to a FF window

I usually have two windows open, each with multiple tabs, and the issue
occurs on both at the same time. I notice in Task Manager that when I
have closed both windows, there is still a firefox.exe process running,
which I must kill in Task Manager before I can restart FF.

I have four extensions:

* Talkback
* IE Tab
* Firebug
* DOM Inspector

Any thoughts much appreciated!
