Internet explore has closing error. the 'X' in the upper right corner isnt there until i try to click it?

when i open internet explore it is fine as long as only 1 page is open, but once it opens a second page the 'X' (close) in the upper right cornet and the min/max ons are not there. Once i putt my cursor over where they should be they show up but not as the correct colors, they show up gray. If i click the X to close out of the window or if i right click on the tab at the bottom and try to close that way the same thing happens where i get a message that says internet explore has encountered a problem and needs to close. if i click send or dont send it does the same thing where all the windows will close. the erroe signature says AppName:iexplore.exe, AppVer: 7.0.6000.16791, ModName: Unknown, ModVer 0.0.0.0 and Offset: 028e0eb0..i have searched for a fix and can find anything. its really annoying. please help
