Mathcad 14 M020 error editing argument field when using function prefix

[Ninetrees]

I imagine that this is already fairly well known...I was using the function prefix today and when I tried to divide the argument to the function, the divide line appeared below the whole expression. I got around this by creating the argument on the page and copy/pasting it into the empty argument field of the function prefix.

I don't think anyone else has reported it on the forums, but you are correct. It's bug, and it still exists in M15.

I think you mean the prefix operator.
