Hi, Hans and Peter,

The line spacing is the default for Body format, when
it is defined with 11-point Arial (13 points line
spacing).

As a troubleshooting step, I tried it on two PCs.
Both are Win2K.  One is a laptop service pack 3 (I'm
not sure about the desktop).  The desktop Monitor
Properties is ATI 3D RAGE IIC AGP, 1280x1024 pixels.
The laptop is ATI Mobility M4, with 1400x1050 pixels
and 16 bits/pixel.  However, the problem persists when
set to 640x480 pixels, 256 colors/pixel.  Note that the
problem only exhibits itself at 90% zoom.

Because the problem is consistent across PCs and video
settings, it is may be an ATI bug or an FM bug.  I
don't see the problem with any other app.  However, I'm
usually using the text editor gvim, or the command line
terminal.

Thanks for checking it out.

Fred
