default font in OGP no longer what I want

Good morning.

I upgraded my copy of OGP 	to 5.2 recently and since the upgrade,  
there seems to be a change in the default font, point size for text  
objects.

Rather than having the text formatted as I'd like, all text is being  
entered in Helvetica 12pt.  I have confirmed that the check mark is  
next to my desired choice when I click the down triangle in the text  
tool button in the tool bar.

Did I miss a changed setting due to the upgrade?

Steps to recreate:

Select Text icon in menu bar
place cursor on canvas where text is needed, left click
start typing

The text entered appears in Helv 12, not the Font/Point size selected  
by the check mark if the down triangle is pressed on the Text tool

Steps to correct:

highlight Helv 12 text and reformat to desired font/point size
