I have java 1.5 installed, seems OK.
However, couldn't install Limewire using the rpm, got
error: Failed dependencies:
j2re >= 1.4.1 is needed by LimeWire-free-4.12.3-0.i386
So I installed using the 'nodeps' option.
Attempting to start limewire now just produces the hovering splash screen, and on
cancelling I get the following message in the shell:
Starting LimeWire...
Java exec found in PATH. Verifying...
Suitable java version found [java = 1.5.0_07]
Configuring environment...
Loading LimeWire:

Something went wrong with LimeWire.
Maybe you're using the wrong version of Java?
(LimeWire is tested against and works best with with Sun's JRE, Java 1.4+)
The version of Java in your PATH is:
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode, sharing)

I had limewire installed previously but have removed the .limewire directory.

Anything else to try??
