Hello, I wonder if I can pick somebody's brains...

I'm a beginner at trying to program in Turbo Pascal for Windows. I have
an application where I want to open a dialog box with just three
checkboxes in it. I managed to get everything working by defining a
descendant object of TDialog which included a method for responding to a
message caused by the clicking of each checkbox individually. However,
this took quite a lot of code to do something really quite simple, and I
read in the manual that I could avoid having to define a descendant
object by using a transfer buffer to determine the states of the check
boxes at the beginning and end of the dialog.

I duly set the thing up, paying close attention to the manual and to the
example program given on the disk. My new program works fine, except for
one thing - when I click the mouse on a check box, the box doesn't
toggle. It registers (i.e. the box is highlighted to show that it is
being clicked), but no check appears. Has anybody else had this problem?
If so, what caused it, and how did you resolve it? I'd be really
grateful for any advice you could give.

Thanks in advance,
