I hope this is the right place to post...
I have been using jEdit on my laptop running Windows XP, and have been very happy with its performance. When I am at work, and connected to the corporate LAN or wireless LAN, jEdit works just great.

But, when I am disconnected from the corporate LAN and working without any network connection, jEdit is extremely sluggish (for example it takes jEdit 3 seconds to respond to and complete pressing the page down key in a 1500 line C souce code file).

Even if I connect to my network at home or to the corporate VPN from my home network, jEdit is still sluggish.

I've disabled and un-installed all plugins to make sure it wasn't something related to a plugin, but this had no effect.

Any ideas what may be causing this ?

Thanks,
Paul
