I'm having a problem with my homebrew channel, I can run applications just fine and everything but when I exit from an application the wii just freezes.. (when trying to go back to homebrew channel) thus forcing me to hold the power button until it shuts off... I've already tried re-installing.

What can I do to resolve this problem?

Some information about the wii...
Version 4.0U
Using cIOSCorps
