Search disappears without searching
 

I've been using Limewire for quite awhile with no problems that I couldn't resolve. Right now I have 4.12.11 for Mac OS 10.4.8. I lost my connection (alll of it - had to restart the router), and when I restarted the computer and then Limewire, I go tthe message that I would need to connect. I chose "connect" on the file menu. While this was going on, a file that had been cued was downloaded to my computer.

When I enter a search term it disappears immediately after I click search - like it was never there. The results screen remains silver, and there's nothing in the search box. It remembers it, though - when I type it again, it's in the history and offers to autofill.

Even so, it continues to download already cued files - I just can't search.

I'm afraid I don't know what firewall I have, but I've made *no* changes since it working last night.

The page should say 'Your test worked!'. It did.
