Custom Procedure issue

I have a .w procedure I wrote that runs a report made in report builder.
First, a large grey window pops up with a small white section in the upper left corner. This section ask for the date range.
Then it shows the report.

The problem is after the report runs, the large window is gone but the small white section remains. It is now stuck in the upper left corner of the Vantage main screen. The only way to get rid of it is to exit vantage. Any ideas why this is happening?

Thanks,

Jasper
