Component sizes change from WinXP to Win 7

[HuntsvilleRob]

Hello. I have an app written in Embarcadero C++ Builder 2010 and tested on a computer running WinXP. Everything works great. However, when I move the app to a different computer running Windows 7 OS, the app works but some of the components' sizes change, e.g.- a string grid which has height 500 and width 500 on the WinXP will suddenly have a width and height of 750 in the Windows 7 OS. Is there a setting I'm using wrong? Anyone else seen this? Thanks.

Check out the font size used there, on HD displays it's often switched to 125% to make text readable again for more 'experienced' (older) eyes
