ShowModal screen position

Hi

I'm showing a second form modally through a button on my main form. I
have the position property of the second form set as poMainFormCenter -
but if I have my main form at the edge of the screen, the second form
is shown half hidden (the rest of it is off the screen). I'm thinking
this would be complicated to solve - I.E: to detect whether the form is
shown off the left of the screen or not, and display it accordingly..?
