I have a better solution for that issue that i have discovered before selling my Axim x50v.
Steps you have to do in order to avoid the infamous MB bug:
Under settings(it resides under the little home icon) you should have 2 small modifications.
Set the Tap and Hold delay for 200ms which is different from the 400ms default, also have the Task Bar set to 4 icons, not sure if the second one has any effect at all, but i like that option better either way, hope that helps. :)
