Re: shade and -gif

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Helge,
There was a bug, which is fixed in the very latest version of Ferret, v5.60.
When starting Ferret with the ferret -gif strartup option, this caused 
trouble
for shade plots made with /HLIMITS or /VLIMITS. 
Please upgrade to v5.60 if you can, and let us know if you still see a 
problem.
Here are the release notes for v5.6 -
