V2.0.1 MINOR UPDATEThis is now available and will need an F5 or appropriate main page refresh/reload to fully implement.
It moves the persistent checkbox options to below the options menu at the bottom of the main MDWS window making them easier to change and so they are no longer available in the Options popup. As a result, these checkbox options are no longer displayed within the graph panes themselves. There is also some rearrangement of the links to make them tidier with Help now a link.
The change is implemented instantly without any refresh but you will need to Refresh (using the button by that name) any graphs that are affected or wait for them to auto refresh to pick up the new setting. The current setting is stored against your user name so is global for all affected graphs. It may be possible to automate the graph refresh later.
There are a number of other background changes and minor bug fixes.
GOOGLE SLOWI notice for the past few days that Google is being very slow to respond at times making it appear that MDWS is hanging/not responding - you can check using the status bar that should be at the bottom of your browser window and will say waiting for
www.google.com or canv.googlecode.com or similar. It's very bad at the time of posting this and may time out eventually leaving a blank graph.
