Reviews -- the tree on the web-site

[RickC]

On our Contributor web-site we have a tree where some of the nodes have subsets and some do not.  After this weekend, if I open a node with subsets everything in the right pane shows fine (that is, I see it and its subsets).  However, if I then click back to a node that does not have subsets, everything is not fine as I still see the old node and subsets in the right pane.

Also, this was applicable to my PC and a few others but not to all in my department.  However, now it is applicable to almost all.  For example, one guy we looked at yesterday was fine but today he is not. 

We are using Planning 10.1.1

Update:  We have been checking things on the PC (internet explorerer, java, etc.) and we thought we found a solution in that some PCs were using an older version of Java ... but that turned out not to be the answer.  Also, we have discovered this is now happening in our Development environment as well as Production.
