Limewire freezes and won't shut down

[miss.cm]

Hello everyone,

I tried looking for an answer to my problem on other threads on this forum but I couldn't find any... So here it is:

After a lot of trouble and a big help from this website, I finally installed Limewire 5 on my MacBook, recently updated to OSX Leopard 10.5.

I am getting along fine with the new Limewire version, but the problem is, I am downloading something and after a while Limewire freezes. I don't see the colored-circle but I can't do anything, even forcing it to quit either with the usual "forcing to quit" neither with the Activity Monitor. The only thing I can do is shut down my computer and start again.......

It is getting quite boring! Plus I really don't want to go back to Limewire 4.18.

What can I do? Thank you for your time and answers.
