Tree view need to scroll to view the graph

[khaldoun]

Dears we had cacti 0.8.7g we migrated it with the database and the rrd files to a new server with fresh cacti 0.8.8c installation.
Polling and graphing is working well but the problem is in the graphs tree mode view. Since we are an ISP our tree structure is huge, whenever we need to see a certain graph in the tree we press it, the graph opens but we have to scroll up to view the graph as seen in the attachment. Note that in the previous cacti version we didn't have to scroll up to view the opened tree graph.

Thanks for the help in advance.
