ugroup grant/revoke weird behaviour

[pwd9370]

I'm using cacti 0.8.8g under centos 6; I recently installed the ugroup plugin. I'm seeing strange behaviour when I try to grant or revoke permissions. The behaviour is very variable, and it's difficult to describe it precisely. I've had the impression that it tends to be confined to the first three or so items in a list, but I could be wrong about this.

Examples of the weirdness:

- under "graph perms", I check a box next to a graph which is listed as "Access restricted", and then select "grant access" and "go" - but the "access restricted" remains.

- sometimes, I click a checkbox next to a graph, and the listing for another graph is highlighted.

- sometimes the listing contains the same graph twice.

I'm happy to raise it as a bug if necessary.
