ddd which version of Java do you have? You can find out by going to the menu bar, select LimeWire icon (next to the apple icon in far left corner), then choose About LW. This will tell you the LW version & the Java version. There's been issues for other Jaguar users also with blank windows on the newer versions of LW. You may need to get an earlier version of LW instead. Send me a pm & I can send it to you. Press the pm button below my post to send me a pm.
