I am having the same problem with 4.10.5 pro (OSX 10.3.9)
When I try to trash something I get the beach ball and LimeWire hangs up for 30 - 50 seconds. It then crashes a few minutes later.

LimeWire 4.20.4 and 4.10.5 (Pro) has crashed at least once every 2 hours (even when I am not downloading anything).

I send a crash report to Apple and LimeWire each time.

It has been almost 6 months since I purchased (Pro).

When will the next version of LimeWire be released?

Will I have to pay to upgrade to a bug-free version of LimeWire (Pro)?

Thanks
