Embedded command button doesn't respond in new window
 

I have several worksheets that have embedded button, combobox, and
option button controls in them. One worksheet has the microsoft
treeview control from Windows Common Controls 5.0(SP2) embedded in the
worksheet. If I have only one window open all the worksheet controls
are active. When I open multiple windows it appears that only the
first window (application.window.windownumber=1) allows these controls
to be active. My questions a

Is this normal behavior?

Are the working controls always associated with windownumber = 1

Is there a way to hide the tabs on a specific window, i.e. so that
users can't select and activate a worksheet that has controls when the
windownumber is 1?

Thanks,
Jim
