Intermittent blank dialog

[shares]

I wonder if anyone has seen this - it shows up intermittently without regard to OS.

The first thing this script shows is a radio button dialog for language selection. Then comes the welcome screen in the selected language.

The attached shows an extra blank dialog tossed up in between the language selection and the welcome. If I click the Next button, I get my welcome screen.

Anyone else seen this intermittent behavior?

Thanks
