User Form Buttons: Delayed response

Hello all!
I am experiencing some odd behavior with a UserForm, the user must click on a button twice to trigger the onClick event.

This odd behavior only occurs when I call the procedure to show the form through a custom menu. When I execute the procedure from the VBA window, the form behaves properly.

The UserForm is a very basic About box to display version and notes. It has a command button for closing it with the following:

The procedure to show the forms:

Please Login or Register  to view this content.

Using the procedure below gets proper response from the command button.

Using the procedure below emulates the call from a menu. This causes the odd behavior of clicking twice to get the event to trigger.

In summary: What gives?

An addendum after some further debugging...

The onClick event is being called when a button is clicked, I traced it using debug.print.

The command to hide the form is what requires two clicks to register when called via menu or application.run

Very odd! Any thoughts?
