Hi there,
I've written a Excel application that utilises a UserForm (containing
a TreeView, buttons, etc). On all machines I have tested this on this
works, but one machine doesn't.

The application references Microsoft Common Controls 6.0 (SP6), and
this is the same file on all machines.

When I try hit the command UserForm.Show on the machine that doesn't
work I get the ominous:
"Error '459' Object or Class does not support this set of events".

I looked at the help for this, and it talks about Implementing and
WithEvents, neither of which have been used.

Does anyone have any idea what causes this error?

Thanks,
James Simm
