For some strange reason tonight, when clicking the brain button it will not expand. A little tab (bar) appears at the top of the screen identifying PB4 as 'Personal Brain' but then quickly disappears.
The only way to close PB4 is to do so through the task manager. I have uninstalled then re-installed PB4 but no luck. I will do this again making sure there are no remnants of PB4 remaining to see what happens.
I am running Vista Ultimate, 4 gigs Ram and PB4 4012.
