Hello, i use Infragistics for Net 2.0 and VB.NET 2005

I want to get the open forms number. I use Application.openForms.Count property to

 get the number of open forms. I found out that in XP it works well. In Vista, when i have the ribbon hide it works well too but 

 when ribbon is visible, i get application.openfroms.count = 0.

Thanks
