Jeff,

Thanks for the follow-up.

I'm finding some of the GetSelectMenuText() implementations format 
coordinate addresses for display. That means they need to use display 
origin transforms so the displayed coordinate matches what the user sees 
on the status line and elsewhere. However, there does not appear to be a 
path from these functions to the EDA_BASE_FRAME class where these 
transforms are currently available.

Might someone more familiar with the data structures and calling 
sequences could suggest how this can best be accomplished?

Seth, I'd appreciate it if you could bring your knowledge and expertise 
to bear.
