Tools > Options > Document Properties keeps resetting after shutdown?

Hi guys,

I have changed my settings for my Document Properties a couple of times and when I shut down SW they are reset when I boot up again.

Has anyone any ideas as to why this is happening as I have keep changing about ten settings over and over.

Also where are the settings for Sheetmetal I thought they were in there aswell?

Thanks

Lee
