Did just find the cause. Operater 'tardation.
Basically have had two folder locations for templates ( the tutorials folder, and data folders ). Going from 2006 to 2007 maintained all my settings ( so I thought ), so folder locations and order of preference were correct in tools-options-settings-file locations. What did not survive the transition was the option for File-new-advanced-template folder location preference.
When I'd edit one template to get the tree size I liked, I'd save it to the default path ( data folder ), which is where I've always put them. When hitting file-new it was pulling templates from the tutorial folder even though the tools-options-file locations settings should have used the ones in the data folder. Clear as mud?.... Again, ultimately, Carlos Mencia would refer to me as Dee-Dee-Dee for having let this get by me. I've done upgrades for 2001-2007 every year. I should have known.
