incomplete display of layout objects

[tomp]

Not sure if this is where to put this, but I'll start here.

A user has transferred my runtime application onto a laptop. When the application is run, field, portal, and button borders do not display. Nor do the 'lines' on text boxes or other objects. I don't think any lines display anywhere on any layout.

The color content of container fields also does not display.

None of these objects uses conditional formatting (I don't think you can conditionally format borders anyway).

Fill colors and text appear to display completely.

No other user has experienced such problems in 8 years of application.

I have no idea how to diagnose the problem, but I have a theory:

The user put the application onto a Windows XP 'Media Center Edition' machine (not sure what that's good for).

Could that be the problem? Or has anyone experienced this situation?Any thoughts as to what is happening?

TIA
