Hi,

I could add a treeview control in a worksheet using the Control toolbox
and it works perfectly. Later on I decided to create the same treeview
control in a userform. I created the form in VBE and then I click Tools
- Additional controls. But somehow, nothing happened, no window which
contained the list of controls appeared.

Then I tried to right-click the Toolbox bar and selected Additional
Control, but nothing happened. Fyi, the menu item "Additional Controls"
is enabled and I open the user form. I do not use VB6 or VB.NET

Does anyone know what the problem is?

Thanks a lot in advance

Regards,

Anton
