[oXygen-user] Why is "Go to definition" so slow?

Hi Folks, In XML Schema documents I can select a type, right-mouse-click, select "Go to definition", and then Oxygen will take me to the type definition. This is a great feature. However, in recent versions of Oxygen, it has gotten really slow. For example, I have a schema file that is 604 lines (i.e., a small schema). I selected a type, right-mouse-clicked, and selected "Go to definition". It took 20 seconds for Oxygen to find the type. Why does it take so long? I remember in previous editions of Oxygen it would take less than 2 seconds. /Roger
