Hi, first of all sorry about my english.
This problem is freaking me out. When I select some text in certain document and then I check the “Underline box”, the underline appears as a blue line instead of a black line. I do not know why and how to solve this issue. Other documents included in the same projects are also affected while others documents show the black line when I hit the box as usual. So I do not have a clue about what is the matter with this. Can anybody help me? Thanks in advance.
