QUARTUS 9.0sp2 SOPC builder visibility problem.

Hi everybody,

When I run QUARTUS 9.0sp2 SOPC builder at windows xp, IPs window in the middle of the SOPC builder, is empty and if I minimize the window and open it again. I can see it, but I still can not see the connection window and there is also still another problems when I do something like scrolling bars, opening combos..

Could anybody help me? Because I can not connet IPs at SOPC builder.
