maybe a image would help?

My issue is the grid only. The fount size is all messed up. The one on the left is correct, the copied is on the right.

Hi Sean,

Can you provide more details/code that demonstrates how you are generating the second window and applying the CSS to the igGrid inside of it? These details will give me a better understanding of your environment and allow me to investigate this issue further.

Also, do you have any inline styles being applied to either of these controls or their containers?

I am looking forward to hearing from you.

Wow if I knew more of what you were looking for I could help but this code is very very large.

Here is how I create the image you see on the left.

Are you thinking the font is getting large because of some kind of inheritance?

turns out it was a cross domain issue. When I load the page in to a blank.html on the same domain it works.
