Hi

i have a strange problem with the open/savefiledialog.

1st Case
===============================================
If i call in my big mdi-application (25 Forms) a openfiledialog or a savefiledialog like ..

If Me.SaveFileDialog1.ShowDialog = DialogResult.OK Then ..

and click inside the dialog at the scrollbar, the application quits with a System.NullReferenceException

If i disable Application.EnableVisualStyles all works fine ????

2nd Case
===============================================
If i build a new application with only one form1 and call the filedialogs like the same with EnableVisualStyles everything is ok

3rd Case
===============================================
If i copy the form from case 2 to case 1 and call the filedialogs from form1 (same form, same code) the application quits like case 1

Application.EnableVisualStyles / XP-Styles is the key for that bug. Does anybody can help

Best regard

Does calling 'Application.DoEvents' directly after 'EnableVisualStyles' help?
