Thank you all.
I guess that is what it is doing.If you are using PocketMirror to sync to Outlook 2003, you may need to change the setup for the task categories. PocketMirror gives you two options for sycning categories: 1) Don't sync the categories so that you can use more than 15 categories on the desktop, and 2) sync the categories, but then you have to limit yourself to 15 categories on the desktop. I expect right now your system is doing #1, but you want it to do #2, so look for PocketMirror settings and change it.
More than 15 categories won't be necessary, so this should be alright.
