I've been running LimeWire Basic 4.9.29 with no trouble until tonight when it suddenly stopped responding to my clicks. I couldn't click on any of the buttons. I could use the keyboard to start downloads, but I can't use it for anything else. I don't know what's going on, because it's highliting the buttons when I hover over them, but when I click, nothing happens. Does anyone have a clue what I can do?
