Does it do this in LHM7? Or just your theme? Because the ReBar in IE and Explorer are different sizes to begin with, making it hard to even them out.
it does it in your M7 and in my theme (the Rebar is based on your M7 theme)
so i guess, you are the only one who can help
until now, i used only 97DPI settings and it worked fine,
now i want to switch to 96 DPI and still use the large Rebar-background image,
(i guess, i've found a way to "emulate" large 97-buttons in 96DPI with my glass B/F buttons)
i rearranged the "band values", so the 96DPI B/F buttons are placed correctly in explorer,
but in IE they are 8 pixels to low because of the different height shown in the image
