[oXygen-user] How to tell Oxygen to abort loading a large XML file?

Hi Folks, I dragged and dropped a large (167MB) file into Oxygen. I have another memory-intensive operation (which I can't stop) going on at the same time, so Oxygen is taking a long time to load the XML file. It's been 15 minutes thus far and the file is still not loaded. I would like to tell Oxygen that I've changed my mind, don't load it. But Oxygen is completely unresponsive. Is there any way, aside from killing the task (and losing all the changes I made but weren't saved), to get Oxygen to abort loading the file? /Roger
