Virtual Graph Paper

One of my virtual graphs' progress is not showing.

This graph used to have a bunch of things on it and now they're nowhere to be seen. Can this be fixed?

Hi,

I'm sorry this isn't working for you. Do you see an empty screen when opening that link? Is the grid visible?
When I open that link I can see many (cool) drawings.
Can you tell me what browser you're using and which version?
