Converted custom form from 11i to R12 has zero height fields

Greetings,

I am working on a custom form cloned from an 11i instance.  Several changes were made in forms developer 10.1.2.0.2 on my PC.  The form is properly based upon template.fmb and everything compiles correctly and generates without errors.  When I transfer and generate the form on our linux environment, all the form fields and buttons are zero height (actually - .001).  In the developer, they are all .25".  I know I've run into this sometime in the distant, dim past, but for the life of me, I can't recall what I did to correct it.  Any suggestions?

Thanks!
