App Framework Question - Can no longer add a form

I had created a simple application framework program in Paradox 8. Then, after upgrading to Paradox 9, was moderately successful in converting forms to a new program using tips from Mike P's Paradox 9 Power Programming guide. Was almost done, when I started getting these error messages when attempting to add a form to a menu:

"objectNew: Couldn't create a new object with prompting.

objectNewFromProperties: Couldn't create a new object from the properties.

objectNewFromPropertiesParadox: Couldn't create a new paradox object from the properties.

formNew: Couldn't create new form.

Could not write to file."

I'm on a NT4.0 Workstation with SP6. It sounds like a permissions problem, but which file? Possibly the menu file?

Thanks,

Ed
