Changing text size

After installing win 10 and then reinstalling all my programs, I can't no longer change the size of the tekst. when typing in other values in the text size box it just jumps back to what it original was. 

This only happends to tekst that is outlise of text box. When changing the text size of a text box it work. Any Ideas? It seems to be just me at the office that has this problem.
