BeLGaRaTh67, did you read my reply, #280, are you running a wide screen wall on standard monitor to have it centered, seeing background color above and below it. Molten is no more hassle than any other skin that has background color set different than what you want it to be. Open Molten in SKS and edit the background color to what you want and the issue goes away.
Sorry that does not work, I am using a WS wall on a WS monitor, it is the whole desktop that is shown in the same brown colour as the Molten skin on a reboot, the only way to get it back to the one I want as default is to change it again after rebooting, it only happens with the Molten Skin, nothing else, so as far as I am concerned it is a problem with that. I have used the Diamond and Leo ones with no problems with my default wall, just Molten as I say, I cannot make it any clearer than I have already said, it only happens with Molten

As mentioned, I like the skin, but am avoiding it until it is fixed.
