I have just very recently started using Framemaker (on Windows). I have two problems that are driving me absolutely crazy and I have to seek help. When writing equations, when I type the parenthesis (or any kind of bracket) in an expression, the content inside the parentheses is biased to the far right (rather than being centered as it should be), making the equation appear ugly--something like "sin( a)". My second problem is that when I input a symbol (say, omega) in an equation, (using the button from the operator palette), Framemaker for some strange reason leaves a large space between symbol and subscript. I cannot live with these problems!
I have the 576 patch installed. I also installed the 'Times' font (which I didn't have at first) which is the default by Framemaker. I also have the 'symbol' font in my system. I just can't figure it out, and it's really bugging me. I would truly appreciate any help. Thanks a lot in advance.
