Toolbar dropdowns do not work

On some Windows7 machines I'm finding the drop down flyout tools do not pop out at all, like the line tools button or rectangle tools. You can click and hold over them but the pop up with the other tools never displays. You can click on the black triangle on the lower-right corner or hold down, neither work. Was this ever a known bug with X4 on Windows7 PCs? Any advice would be appreciated! Thanks
