UI settings resets?

[AnAnimatedCorps]

Hi all, I've used default ui since the game released and after much badgering from friends DLed prophet. LOVE IT. Its the best, I feel stupid for not having it sooner. As happy as I am though, I am experiencing a bit a of an issue.

Seems every time I restart EQ2, or every so often, my UI completely resets, moving my hotbars to the oddest places which is getting to be a bit frustrating when trying to down Tangrin =/

Sometimes when I log back on, they're back to normally- what in the world is happening to cause this?! Any help would be appreciated..
