RE: Window format clearing the remainder of the screen

No messages of any kind in the compiler listing and all formats are in the
same display file.

The DDS source follows:

Are you sure the display files are identical?  It may be due to a PTF
difference but I couldn't find a match for your symptoms.

Is the record format with WINDOW in the same display file as the format
being overlayed?

Are there any warning messages in the DDS compiler listing?

Can you post the DDS source?
