Sounds like you might have some type of softw conflict.
What you can try is:
1. Repair LimeWire using the Add/Remove Programs utility
2. Right-clicking the Limewire icon and going to properties and changed compatability setting to Windows 2000.
3. Update your Java
version 1.4.x OR
version 1.5 (take the JRE)
4. Trash the LW Preferences folder called .limewire (whilst LW is closed!)
How much ram do you have? By the way, did you check your bug report
instructions & sample image & is it True/False? Are there any errors showing with Java? Did you use the english or international installer? Try the above & see how you go.
