Re: [ferret_users] Why plot/thick=2 does not work sometimes

[Ge Peng <gpeng@xxxxxxxxxxxxxxxxxxxxxxx>]

More tests reveal the following:

plot/line=8 var1 crashes only in a ferret -gif session but not in a ferret
session using v6. But plot var1 works fine in both sessions.

With help from the system adm, I am able to do tests using an older
version (v5.80). plot/line=8 var1 works fine in both ferret and ferret
-gif sessions.
