Downloaded the latest development source and found
the apparent shaking of text window & stats line due to
Also downloaded the latest offical release (version 5.3)
and didn't find so serious problem.
Problem exists in SGI, Sun Solaris and Linux
To observe that, just open a blank file with nedit and
hold the "enter" for a relative long time, as the cursor
goes down, you may observe the shaking I mentioned.
