Mal - Have you had any problems with Shell & WP?
The last couple of days my Treo freezes up on start up after a soft reset. Taking WP out of a tap fixes the problem. I am thinking it's a WP problem though, as installed themes and icons are not showing up when in WP settings. And yes they are in the right folders. The default icons are not showing up in the themes when selected. Also I have tried to reinstall and tried a few a couple of the different CABs here.
