Care to explain what we are looking at? ;-)
Most fonts should display the text in bold (select them via the View > Font menu). The default Verdana font has no issues with it.
You're right! With Verdana, bold text is displayed as bold. With Arial or Arial Unicode it isn't...
I'll record a screencast about this.
Igor, what font are you using to have bold displayed in the grid? I'm using Arial or Arial Unicode and don't get bold.
