RefEdit problem: z-order of forms change
 

Hi,

I'm developing an Excel VBA application.
Platform: Win 2000 with SP4, Excel 2000, VBA 6.0.

I have a form (FormA) which has a button to open up another form
(FormB). Both these Forms are Modal. There is a RefEdit control on
FormB. When I click the RefEdit button, the forms disappear as
expected, and I'm able to pick a cell. Now, when I click the RefEdit
button to display the forms again, FormA is shown on top on FormB !!
Why does the z-order change?? Please help !

Thanks,
Shankar
