Sorry for the extremely vague thread title, but I had no idea what else to call it.

A lot of people have had this problem where loading any Homebrew app leads to a black screen, with Wii remotes turning off, having to power the Wii off at that point, the solution to which is in the Black Screen thread on this board.

I'm getting something very similar: when I power my Wii for the first time that day, it works perfectly fine, but after the Wii is turned off once, I'll get the black screen on loading. So it works once and then afterwards, it won't work anymore for a few hours.

What could be causing this?

If it helps, I'm on System Menu 4.2 and Homebrew 1.0.6. (It COULD be .7 or .8, not sure. If it matters, I can look it up.)

Thank you so much in advance!
