Saving .dotm from 2007 to 2010 causes form property changes

[Paul1]

I posted a problem entitled "Form frame is blacked out in Word 2010" in this forum on 23rd August. I understand now that some changes were made by Word itself when I saved a .dotm file originally created in 2007 as a 2010 .dotm file and opened a document based on it in Word 2010. The main change was the form label backcolor property from white to black and also some form font sizes.



Is it a known problem where Word makes internal changes to file objects especially form objects when converting a .dotm file orignally created in 2007 to 2010 or is is this just a local problem?

NOTE. These objects were defined in the form Properties window under Visual Basic in the Developer tab.
