WinStudio
WinStudio supports a built-in script editor for Visual Basic, or, if Microsoft Visual Studio is installed on your client computer, you can choose to use the appropriate version of the Visual Studio IDE as a script editor.
NOTE: The check box is selected by default
to improve load and compile time of scripts in run mode. To edit scripts
in Design Mode, you must clear the box to prevent assembly-locking
and memory penalties.
If a form is open when you change this setting, the setting reverts
