I created a Userform that has on command button on
top. When the command button is pressed, my code
will toggle/resize the Userform's height between 100
and 200 pixels.

I notice that sometimes when I press the command
button to initiate a resize subroutine that userform will
not always immediately resize. It's almost as if the
button press event gets lost or the resize fails. Why
is there sometimes a delay or lack of resize when
a command button is pressed??

BTW, when the command button is pressed I will
usually just run the following code:

UserForm1.Height = 100 ' or 200

thank u
