------- Additional Comments From ross@stationplaylist.com 2006-29-09 03:21 ------- I can confirm this. We have had to modify our software to hide the splash screen when asking for registration details, otherwise the registration form is not visible and is sitting behind the splash screen.
This seems a very important bug. It must affect almost every Windows app that uses modal forms, and I'm surprised it was not fixed years ago.
