Alerts: Changing position on Objects list causes List Index error


Q:  My background color is set to black.  I create a lot of alerts but I do not want a color to appear on the chart so I set the color of the true alert to black.  After a period of time setting up alerts this way a problem appears.  When I look at the chart objects and select one and click on the up or down arrow to move the object, I get the error "List index out of bounds(4)"

After considerable troubleshooting, I discovered that if I change the color of the true alert to anything but the color of the background color of
black, then it works. It looks like the software did not take into account of having the same color on both the alert and background.  When I have this problem, weird things happen.  Some study flags and fields disappear etc.

A:  I do not think the issue is related to the Show color being black.   The issue is you are moving the alert up or down the objects list.  The alert is referencing other studies for values and flags, and the other studies MUST be ahead of the alert on the objects list.  The error happens when you move the alert ahead of the referenced studies, because then the alert cannot find them ahead of itself on the list.   That also explains why the alert loses the content of its study flags and fields.
