Question winforms app developed on 32 bit trying to move to 64 bit machine

[Darren Shafer]

I am working on a vb.net winforms application that compiles against the 2.0 framework. My issue is that I am running Windows 7 32 bit machine and my app works fine but when the code is copied over to a Windows 7 64 bit machine some of the controls on the form are strangely disabled. In Project Properties it is set to compile as x86 target. Has anyone experienced a similar problem and does anyone have an answer as to why I am having problems on the 64 bit machine?

Thanks
