Can't edit text in any way

As stated in subject, something very wrong.
I can't edit any text in drawings (new or presents drawings) with any command (edit or ddatte) nor double click on text.
No different if normal text or annotative text

I guess some vital systemvariables must have changed. (how i cant figure out?)

Any tips on what variable to change or search for?

Win 7 and bricscad 15.1.20 
/Thanx
