Thank you for the explanation in previous email and this code.

Got it all working for my use case, but a couple more issues.

1) I am using a fudge factor of 24 to account for the combobox drop down

arrow button. I can't find a pixel metric for it. Is there a better way 
of getting the width

Its part of the style.  I cant remember off the top of my head, but
there is an enum that you can query the style for to get its pixel width
for combo boxes
