We have 1 file that when loaded, shows the correct font style (mtext). However, when switching to another tab or editing the text (or even a regen), all the text on the drawing (paper space) switches to another font - but it still shows the correct font in properties or editing (_mtedit).

Once this drawing is opened, every drawing opened after that also has this problem. They don't show the correct font unless you restart autocad (07, or even 0. This is on every computer in our office.

Another thing to note is that there is a DWG from Revit as an xref under the text. This is the only drawing with this problem, other revit DWGs are fine.

Ideas?
