It's a "feature/bug" of split windows.

Maybe you can use freeze panes and put the control at the top???

Good afternoon --
I've designed a workbook to have checkboxes on two worksheets. Then, I
wrote a macro to open the workbook in two tiled windows (so that reference
info stays visible in one window when the other scrolls as the user adds more
info).

My problem -- the checkboxes on Sheet 1 work fine, but the checkboxes on
Sheet2 don't. They only work when I switch to the other window and go that
same sheet Whoda thunk?

Very simple code. If the box is checked, place a value in a particular
cell. But the box is unresponsive on one (active) window and, when I make
the other window active and go to that sheet, it works just fine. Any idea
what might be happening here?

TIA
