In some circumstances proofing fails when using FlexProof/E with a SmartMark displaying the Color Strategy's name.
Symptoms
When trying to proof, the task errors with the following message:
ERROR: bgfrm.nonsupportedcolorstrategy("[name of the proofing strategy]")
ERROR: bgfrm.failaddjob
ERROR: CTicket2Dict_frprooftask::AddJobInfo - Non supported color strategy
Solution
Make sure your strategy has no space or special characters in its name.
