Delphi DBGrid missing scrollbars

I have a list of contact records displayed in a dbgrid.  Works fine on my system, but the client is reporting random problems on multiple machines with the vertical scrollbars not appearing, so they have to use the keyboard arrows to scroll up and down.  

The contacts are detail records. If the user scrolls through the master records, the scroll bars on the contacts grid appears on every other master record, irrespective of the number of records being more than can be displayed.

Comctl32.dll is usually the first point of suspicion, I am using 5.82.2900.2982, the client is using 5.82.2900.5512. I don't seem to be able to find what version I should be running.  All machines running XP Professional.

are you switching the scrollbars on and off by code ?

see this thread:

Even though that bug report is marked as "Status: Closed" and
"Resolution: Fixed", the bug is still present in Delphi 2009 with
updates 1 and 2, which is what I'm using. I posted my experience on the
web page you suggested.

The workaround did the trick, however:
myGrid.Align := alNone;
myGrid.Height := myGrid.Height - 5; {kick in the shins}
myGrid.Align := (restore original align)
