Delphi has left an over sight out in all in their code
This affects TGrid and its descendants directly (TDBGrid).
The real problem is when Microsoft removes the old Windows 98 API calls in (expectantly) Windows 8, your Delphi code certainly will not run at all final on the new Windows!!!!!!
I think its going to affect every project of Delphi regardless because the calls are so perverlant. (test it with my kit on your web site)
Please visit my web site under construction and download my kit to help you evaluate for your self of the implications that would be incurred.

One last thing, if a mechanical part fails on you, sometimes you can get a little bit of noise back into it by yelling at it, kicking it, or pounding on it with your fist. This might put enough back into it so it will work for a few more minutes. - KenWittlief [more]
