[hobbit] little bug in zooming graphs?

Hello folks, when I am checking the disk fs graphs and trying to get a detailed view with using the zoom (little loupe on the right side of the graph), I get the view from an other disk instead of the disk for what I am looking for. e.g. I am interessted in /nfs/exp, I am using the loupe and get the graph from an other filesystem like /aldv/*

it is switching the view to

[Hobbit Monitor 4.2.0]

Any ideas?

Regards, Klaus
