Issues with opening windows from a tree

I am having issues when I logout of a project and log back in that when I select a window from the tree it will open that window but it will highlight random windows in the tree. If I try to open the random window in the tree that it highlights it will not open because it thinks that window is open. This will happen 4 to 5 times then the issue goes away until I logout and back in. If I switch user this issue does not happen, only logging out causes it to happen.

Is this a bug in the system?

What version of Ignition and Java are you using?
