Hello,

I have posted this on usenet, as well as tried to inform MS about this. Hopefully someone in this group will pick up on it and give it more priority with MS.

Steps to reproduce:
1)Create a grid class with the following properties:
Height=20
HeaderHeight=0

2)Change your windows font size to large or extra large.

3)Edit the grid that you created in step 1, and you will get the following error:
'Expression evaluated to an illegal value'.

This occurs if you open up a form in design mode as well if the grid is a member of it. It is a design-tip bug, and a showstopper bug at runtime.
