Jurek,
The color scale should be sticky, i.e. one of the database
records in the TPM holds the scale factor (tpm_TM_Scale),
so opening and closing the display _shouldn't_
change the color mapping from the last time you set it.
The scaled differences are recomputed every time the TPM reads
the data from the temperature micro. Once every 2 seconds
the TPM performs a quick succession of block reads from the
tmicro - which would explain the transient behavior after
changing the scale.
I'll ponder the communications issues with the watcher. Any
comments from Fritz, Craig, Robert?
