Well... I've never ever heard from that issue, I'm testing efxMod on different resolutions, starting with 1024x768, 1280x1024, 1280x720, 1440x900, 1680x1050 and my main desktop res 1920x1200. There weren't even bug reports by anyone regarding such a graphics bug.
Please, can you post a screenshot or email it to me?

Well, this has been described before - the extended gui isn't finished yet - at least, some of the Buttons/Sliders are not linked with efxMod functions/features.
