I am also experiencing these issues. Also, Edge just hangs out for awhile without any indication of what it's doing. I have also gotten pop ups telling me an error has occurred and I need to save and restart the program.
This happens for me on old files and if I create a new file and do anything to it.
One last thing, if I attached the jQuery UI script it will not get loaded or used unless I also attach all of the .js files in the downloaded folder. I actually could not get the 1.11 version to work at all.
