Delphi, application scaling, Windows 7

Good day everyone.

I have a problem with Delphi 7 application being used for Windows 7.

It works perfect for older windows like XP, but on Win7 the form is scaled to higher dpi which completely breaks everything on the form.

So, my question - is there a way to fix it to work correctly on win7, or to somehow completely disable scaling?

I tried to search, but couldn't find anything that would work for me, and I would really appreciate your help.

I saw this phenomenon (as a hired consultant) on XP with Large Fonts on a (then) big 22" about 2003: Buttons on an MS C++ application disappeared to the right outside the form. At the time, the developers (500 kms away) had never seen this phenomenon before.

I recently solved similar problem in my D7 by:

  1. Setting large fonts on the old developer machine and fiddling with the (rather medium) form size to accomodate visible components. However, setting large fonts made the old win2000 crash and never completely recover...
  2. On more modern machine (XP with D7), I set a Scaling property to False on Form1 with good results, i.e. the fonts were smaller. The program(s) in question run on a couple of wall mounted touchscreen PCs preinstalled Win7 with incredibly large fonts (because it's a touchscreen).

I can't find out a better method than to temporarily set Silly Large Fonts on one's developer machine and see what happens. (I see there are many related questions here now!...)
