backcolor of button lost when exe run on other computer?

Hello,

I built a .net windows forms app which looks fine when displayed in Visual
C# 2008 Express edition, and when the .exe from the release folder is run
directly on this same machine. However, when I run the exe on another
computer, which has the same operating system as the dev computer (both
server 2008), two problems occur:

1. the button's loose their backcolor? (which makes the text unreadable)

2. the form opens very small and has to be manually resized?

I have not really messed with a windows forms app since vb4 I think... so
its fair to say I'm new to this.

any input would be appreciated. thanks.
