In Firefox I noticed that there are some memory leak when you open and close a lot of project instance,
In other words memory heap steadily increases and it seems that browsers like firefox never release memory resources (I have tried this on your demo web site).
I would like to resolve this issue, but I think it won't be easy.
Do you have any suggestion on how to fix this kind of problem?
At the moment I already tried to destroy all the tab panels involved in the closure of a diagram but it didn't work.
