Thanks for the quick response.

I had already looked at task manager to see if any processes were gobbling resources. However, i could not see any differences between:

1) before limewire started
2) while limewire was running
3) while limewire was running, and HD grinding was evident

I had thought that maybe something was gobbling memory, and the page files was being used extensively - but this is not the case, nearly 200Mb of my memory is free and my page file size remains at a constant ~370Mb.

I currently have JDK 1.5.0_06 installed. However, i will follow your instructions to remove this but will install JDK 1.5.0_07 rather than the JRE. I will post again when i have further news.

Cheers
Nathan
