Force deletion of temp menu bar

[Roy Lasris]

I have created a temporary floating menu. I added a button called 'Close' which
I (think I) need to be the only button that the user can press to get rid of
the menu.
The 'Close' button reassigns a button, and that is an essential step in the
process.

(1) Is there a way to disable the 'x' button in the upper right corner of the
floating menu so the user must press the Close button or

(2) Is there a way to indicate to Word that the menu has been closed via the
'x' so that the same steps that the 'Close' button performs can be
accomplished.

Thanks.

Roy
