There are two ways to to disable this feature on the Add screen.
First, individual workstations bring up the Add Data screen and press the CTRL+ALT+SHIFT+F9 together. This will toggle the feature on and off. A message will be displayed on the screen indicating the current status of the feature.
You would need to do this to each workstation you wish to disable the feature for.
The second option would be to edit the QW.IQW file with Notepad. The file is typically located in C:\Progdata\Busitech\QW50 directory. Under the Settings section make the following change:
F9DISABLE = FALSE
You can then copy that file to all the Workstations you wish to restrict the use of the F9 Copy on.
