There is an extreme problem with the connection between the individual program and the calendar.  When a workstation makes a change to the calendar (add, modify or delete an appointment) when more than one work station is running Lacerte, it causes the whole program to become sluggish.  When the workstations that were running restart Lacerte, they go back to normal.  We have spent hours and hours with and without Lacerte techs and still the problem continues.  Any one else with the same problem.   Would Lacerte please check to see if there is a programing error!
