Have you tried changing skins? I had a skin that used to do that and I just switched to a different skin and now it stays on that skin and doesn't go back to default anymore.
Just updated to akaio 1.8.5 and it works just fine. No problems at all. Thanks again for another awesome update....and I use a cheap sandisk class 2 8gig card with no problems. So I don't understand why anybody should be having problems.
