Micheal, I was back at a job today that I have not modified at all except for updating to the latest release of JFIELD and it is definitely slower on the zoom out and in function versus the previous release. It is a job that has quite a few lines and points in it, but previous release was much smoother and quicker. It now seems to lag and freeze for a few second before it catches up. I just wanted you to know that I did confirmed what I reported earlier. Thank You for your hard work in resolving the issue.
