Thank you Mike for reporting this problem, and for your patience with
this issue.
Recently I believe I have discovered a simple code change that
alleviates the excessive CPU usage related to the progress pulse bar.
Would you be able to test the following patch to see if this provides a
performance improvement?
Thanks,
Curtis Gedak
