The wrong display of radical sign

[darkjoke]

Hello! I'm a new Chinese user who just met OpenOffice a few months ago.
Recently I met the problem of OpenOffice Math. When I want to input the formula which include the radical sign, it will be showed as the one displayed in the e-mail attachment. So I hope someone can slove it. I will appreciate it.

Hi and welcome to the forums.

This is what I see:

Is this what you expected?

The <?> tokens are just placeholders, to show where an operator needs operands. You should overwrite them, to have something like nroot {n}{X}.

The reason why the root sign is not displayed correctly: At the current size/zooming level, lines are narrower than one pixel, and Math does not compensate for limitations in the display device (by using "pixel alignment hints" present in some font files, antialiasing, or somehow forcing a minimum line width to ensure visibility).

The root sign is in there. You can zoom in to see it resurrected (View - Zoom, or right click the zoom box in the status bar at the bottom of the window).
It should be OK when printed, too, because printers generally have finer resolution than computer screens.

Thanks!! I hope I'll make it by your method!!
