Sigh!

Thanks Jacque, after I emailed the question I worked this one out but
it was so awful that I hoped there was a better way...

Ah well, at least it works.

For anyone wanting to know the full details, here is the full script I use:

    put the topleft of btn "Tabs" into tL
    put the screenmouseloc into tOldMouse
    add 10 to item 1 of tL
    add 15 to item 2 of tL  -- move right & down to avoid the corner
    set the screenmouseloc to globalloc(tL)
    put the mousecolor into tCol
    set the screenmouseloc to tOldMouse
    set the backcolor of fld "Status" to tCol

After setting the backColor or the stack, you can't do this instantly
as it takes some time for the tabbed backgroound to be updated. I call
this 5 ticks after setting the backcolor and that seems fine. 1 tick
worked most of the time on my 2 GHz iMac, so hopefully 5 will be safe.
I might push it out to 10 as the field I need to set will not be
visible when this change is happening.

Thanks,
Sarah
