Display blank parameters window for a custom report?

I completed a simple utility today that requires no parameters and outputs a single cell of data to an InfoMaker report.

It appears that when a report is configured with no parameters, it runs immediately from the "Select Report/Utility" window instead of displaying a blank parameters window first. This strikes me as dangerous because most users will expect the parameters window to display first before the procedure will actually run -- a confirmation of sorts that they've seen from every other report. What's more, this utility updates data (removes remaining false positives from T_POTENTIAL_DUPS), so it would create a hassle if it is done by accident.

I discovered that I can add a blank parameter to the report setup to trigger the parameter window display, but I would have expected this instead to have respected the "Param Win" setting in report setup. And I could have sworn I had seen a blank parameters window before...

Does anyone know if this can be accomplished?
