If a user customizes a timeperiod for a screen with graphs and then views a graph on that screen, the timeperiod is stuck there until the profile table is cleared.

For example:

1. User selects "All" for current node.show all nodes are showing.
2. User goes to a screen with custom graphs.
3. User changes time period to something in the past.
4. Let screen refresh from automatic refresh settings.
5. Now click on a graph on the screen to bring up the graph directly.
6. Let screen refresh.
7. Try and drag the time bar to "Now".
8. Let screen refresh and you will notice the time will jump back to the screen time period selected in step 3 above. On way to fix this is to clear the profile table in the database.
