Anyone else having intermittent problems with mouseover windows not appearing? The secondary mouseover popups that describe Wonders, Units, and Buildings when the "build completed" menu pops up; the description of Techs when the "Reasearch Complete" menu pops up; and in the diplomacy screen, the attitude summary popup when hovering over the leader's face-- all of these will suddenly quit working for several minutes. Then, again without any indication why, they will start working again. Additionally, this popup failure coincides with the mouse wheel no longer scrolling. I have a basic ten dollar MS optical scroll mouse-- nothing special there. AMD64 3300+, 1GB RAM, Nvidia GeForce FX5700 video, WinXp-- nothing odd there either. I'm going to try a different mouse and driver just for the heck of it. Anyone else run into this?
