Hi all developper.

I need your help because i would like to implement your beautiful and great Ribbon but I have a big problem with the option DropDown on RibbonButton.

My functionnal Ribbon

If i change the RibbonButton on "Compression" panel to Dropdown style, RibbonTab2 and 3 disappear and olso:
  • Découper Panel
  • Vérifier Panel
  • Rafraichir Panel
Here the result of activate dropdown style

Worse, when I debug, and when I flying the title of RibbonTab1 i've a NullExceptionRefference: The reference of object is not defined in an authority of an object.
The highlighted code has no relationship with the ribbon.

I have to try on a project new and the problem also arises.
I use your System.Windows.Forms.Ribbon35.dll in 3.5.8.0 version with VB 2010 Express.

Please, said me that you have already met this problem.
Because your ribbon is simply brilliant and I want to continue to use it.

Thank you in advance.
