[SAC-HELP] SPARC/Solaris to PC/SuSE problems

[jim at okgeosurvey1.gov]

We have changed from SPARC/Solaris to PC/SuSE Linux.
Since this change we have several problems with
SAC. The problems persist for the following
versions of SAC: 00.59.48 100.00
and the following SuSE OS: 8.0pro,
8.2pro 9.3pro.

Problem 1. Whenever a SAC graphics 
window is covered totaly or partly,
and is reexposed, the reexposed 
parts are blank. Putting the
window "always on top" or frequent
replotting are the only workarounds
we have found.

Perhaps this is an XFree86 
config problem. I have not found
any other application which acts
this way.

Problem 2. After "plotpk" the
SAC window will only display a
small "+", not a full crosshairs.

Problem 3. I can't use rollback.
It always gives "out of memory"
and sometimes other statements.
Because most of our Linux boxes
have ca 1GB RAM and ca 1GB swap,
but will not rollback even one
tiny SAC file, I do not believe
we are truly out of either RAM
or swap.

Problem 4. The "color" statement
seems to have little or no effect.
I seem to only be able to plot
black and white.

Problem 5. Help followed by a
SAC command which is mispelled
exits with "segmentation fault".

Help!!!
