Thanks, Nancy. I tried to put set step on just before release oProgBar and I experiement with thisform.lockscreen. I found, that grid.MyForeColor fires lots of times, then release of progress bar was executing properly, however, this ghost was still there. So, I was keep trying, until the last piece of code, which seemed to solve this annoying problem.
