The highlight bar on the graphs has wrong position when there is a horizontal scrollbar on the page (or the right pane of the page) and the page or the pane is scrolled to the right. This affects all browsers.
i'm pretty sure this is a duplicate - attach a screen snapshot to explain what you mean. Search JIRA for this issue too - I think there is one or more in here.
This bug was previously known as http://jira.rhq-project.org/browse/RHQ-1856
Temporarily adding the keyword "SubBug" so we can be sure we have accounted for all the bugs. keyword: new = Tracking + FutureFeature + SubBug
making sure we're not missing any bugs in rhq_triage
we won't be fixing this - either a) maximize your browser window or b) wait for us to impl a better gwt graphing method (to be done in the future)
