The problem is not 100% reproducible but they are consistently happening - most of my efforts so far has been concentrated on working with modules and pretty much every time I do something like double click into an artifact cell to edit, or try to insert a new artifact into the module hierachy or try to move an artifact in the module, it will just lock up and I get the "Error on Page" status in the bottom Left Hand corner of the IE browser. Perhaps locked up is not entirely the correct description - you can still hover over parts of the screen and click on the pencil icon to get a context menu, but selecting anything in the menu doesn't work, it's almost like the scripting for each menu item has frozen. Could this be security settings on IE?

The only recovery is to close the browser and start again. Using the browser refresh sometimes worked but discovered that was stacking up memory resources as it wasn't freeing up the memory from each successive lock up - so eventually ran out of memory resources.

I tried your project but I do not have rights edit anything.

I added you as an "author", so you now should be able to edit.   If you have access to another browser (e.g. FireFox), it would be interesting to see if it behaves better.  Note: I'm not a DNG expert, so I defer to the DNG experts for more specific guidance.

 Hi Geoffrey - I tried FireFox version 27 and it works fine, so not sure what the problem is with IE 8.0. Thanks for your help.
