thank you so much for your last hint : all unsued categories are now gone !!!
May I disturb you with another question ? I also have following issue
1) I would like to sort my tasks by "subject"
2) so I select only one category and set the filter to "sort by subject"
ISSUE : TouchDown does not sort the tasks by "subject".
Any Idea ?
(Mybe I shall open a new thread for this issue)
