Description:

TWin32WSCustomCalendar.HitTest returns 0 in unthemed application on Vista and up

Steps to reproduce:

Create an application with themes disabled and ru it on Vista or higher:
-Invoke a CalendarPopup or CalendarDialog.
- Click or Double click on a date
- Date does not change.

TCustomCalendar.HitTest returns cpNowhere wherever you click.

Additional information:

The MCHITTESTINFO structure seems to not only depends on Windos version but also on wether or not the application is themed

It seems this works:

  if (WindowsVersion >= wvVista) and (GetFileVersion(comctl32) < ComCtlVersionIE6) then
    HitTestInfo.cbSize := SizeOf(HitTestInfo)
  else
    HitTestInfo.cbSize := 32;

Needs more testing.
