This functionality is supported only if you are using the Classic Agent.
If you record a click against a Sheridan command button, which is handled by the OLESSCommand class in 4Test, Silk Test Classic does not play back the click and records an error in the results file for the test.
The cause of this behavior is that the OLESSCommand should be a windowless control.
To record the click, edit the class declaration for the OLESSCommand class in the VBclass.inc file, to have the class inherit from the WindowlessControl class instead of the Pushbutton class.
