Form Region Freezing

[Matt]

Hello,

I have developed a small/simple form region to pop up after an added button
click (which is added in Outlook new message window). The Form window loads
in the correct location/size but none of my fields are visible and the form
continues to load until the window becomes non-responsive, forcing me to exit
Outlook. How would I go about solving this issue?

Thanks

Any help is appreciated please.
