Hi. I am a windows user with the same issue. I couldn’t get how I can solve the problem. I think I need to open File/Page Setup menu to open comment syntax part (manual 24.19.1). However, it crashes when I try to open Page setup. The case has reported in the forum.
My question is , is there any solution we can generate for that case. Backslash has highly used for LaTex formulas and when I compile to LaTex create mess. Thanks a lot!
