I am having the same exact problem...I even bought and downloaded the "pro" version hoping that this would correct the problem...no go.

I suspect that this problem is related to the fact that LimeWire for OSX seems to be unable to "remember" preferences, although this bug seems to have gotten a bit better.

Does anybody know how to force the retention of prefs? Or perhaps there is a way to edit them outside of the LimeWire interface?
