Calling FormRead() in a Cicode function that displays a form containing a Combo or List box can be extremely slow as each item is selected as it is added to the List box. 

In the CITECT.INI file add the parameter:


This parameter will stop each item from being selected as it is added to the list box.

The default for this parameter has changed in version 5.0 of Citect and additional improvements have been made in the speed of adding items to the List (or Combo) box. If you want items to be selected as they are added to the boxes in Version 5, this parameter should be set to 1.  Version 5.01 of Citect has additional improvements over previous version in regard to the speed of the form system.  This parameter defaults to 1, and should not be changed in this version.
