I have been asked about this before and yes, it is by design. Use the following steps if you have an Amicus Attorney V client system / user that is unable to delete items from their own calendar. Open Amicus and go to File -> Preferences. Click on the Calendar tab and then click on the Display sub tab. At the bottom of this tab you can adjust the settings to your personal preferences. In most cases is is sufficient enough to just uncheck the box labelled “Calendar pages cannot be altered once they are more than xx days old.”
This issue arose recently after enabling synchronization between Amicus Attorney V and Worldox GX. The symptoms of the issue are extremely slow load times for Amicus when Worldox is open. The issue is not present while Worldox is closed. The quickest way around this issue is to prevent Amicus from trying to sync automatically on load. You can disable this auto sync by following these steps. Start by closing Worldox from the system tray in the lower right hand corner. Open Amicus and go to File -> Setup. Next, click on the Document tab and then the Shared Documents sub tab. Finally, under Worldox Intergration, uncheck the Run WORLDOX synchronization on startup check box. Synchronization can and should be done manually from this point forward.
