Easy to install and use.
1) Ridiculous default column orders & widths within "Tasks". Resizing & reordering is allowed, but discarded on exit. 2) Apparent inability to quickly copy an appointment & paste to a new date (right-click, copy not available), thus requiring to edit, select copy, interface with calendar which lacks correct default, and is way too much work when a simple right-click, copy, paste would be great. 3) After editing or creating a calendar entry, you're not returned to the calendar where you started unless the calendar tab is the only one displayed at the time. 4) Task type cannot be changed & is set to "DEFECT" on all tasks. For some unknown reason, on another system, only some items are set to "DEFECT". 5) Tasks disallow a blank start date for some reason, yet a blank due date is allowed. Although the "To Do List" is better suited for this, however, such items cannot subsequently be deleted (see number 6 below). 6) In the "To Do List" tab, the "Done (Delete)" button displays an error message instead of performing the action. Right-click, "Done (Delete)" produces the same poor result. I have found no way to delete these items. 7) Drop-down combo boxes tend to close during interaction if not going really slow & being really accurate with the pointer. 8) Can't add anything to the description ("Subject") of an existing recurring appointment without it changing all occurrences. For example, you can't document time spent on each occurrence individually.
Installed on 2 linux machines successfully, but printing on both machines will not print the first days of the month or the month name. On windows, DB gave errors but printing worked.
