In various eclipse clients (Rational Software Architect 8.0.3, Rational Team Concert, 4.0.2) when I try to maximize any view, it hangs my Windows 7 laptop for 2-3 minutes. Eventually it just finishes and returns control and I can continue as if nothing has happened, but the first time I maximize a view after restarting, this happens.
I would have thought it was a problem with that application, but since it happens it two different Eclipse clients (they are in separate installation directories) it seems like it is something common.
I can't do anything when the hang happens (process explorer will not come up, CTRL+ALT+DEL does not respond) so I can't tell what is hanging.
I have asked other members of my team and they haven't experienced this so I am hoping to find more ideas with a wider audience.
I had this problem with the Rational Publishing Engine (also Eclipse) and I fixed it by disabling animation in the Preferences>General>Appearance
menu.
This screenshot is from a straight install of Eclipse but I am sure it is similar on the tools you have:
