I have what is probably an easy and silly problem to resolve but I've never come across is before and don't know where to start… other thank asking for help!

My Treo 680 forgets its category customisation as soon as I leave the application. I can set up some pretty colours for the text and background, have everything looking how I'd like it, then as soon as I jump back into Datebk it's back to plain fonts.

Perhaps reinstalling the application is all that is needed? But before I try this or drop Pimlico an email asking for help, has anybody any quick and easy solutions?
