Have tried to look at graphs using firefox on two PC’s but in both cases the graph never appeared after pressing the “toggle graph” button - just a ‘loading’ bar in a box.  Waited several minutes, no joy.  Had a quick look in IE as well but couldn’t bear the pain for long, didn’t even see the full screen / toggle graph buttons on the control panel so gave up.

So we can get to the bottom of the problem can you upload a screenshot of what you see?

Hello Nick, my apologies - the issue is with an out of date flash player I think.  Just tried on yet another PC with newly installed firefox / flash and it works perfectly.

Glad it’s all sorted.
