Range Slider Locks up

I'm having the problem with a combination chart locking up on the initial load of Xcelsius. Hovering over the graph for values doesn't work and the Range Slider is not available and occasionally doesn't go to the end of the chart. Clicking on one of the options built in the dashboard which refreshes the data seems to solve the problem.

The Beginning and End range of the slider is set at position -1 and 100, respectively.

Has anyone run across this issue.

Thanks,
