Disappearing UI pieces?

[Vivisect]

Anyone else have this problem? Once i load a custom UI, and get everything situated, it seems that some windows dissapear on my next login. One of the windows usually is always the maintained buffs window, and also various pieces of different interfaces.

The windows are there on a new install, but not after my next game log in. It's happend with every single one of the interfaces i've downloaded here, reloading doesn't help.

You know I often get my maintained window lost somehow or another Alt-M gets it back but I cannot figure how it goes poof, Also I often get extra chat windows over top of my one I set up too. The playing with ALT-(Every key) and see what goes away and what comes back then you'll get a idea of how to bring them back up! Hope I helped a tad.
