I thought folks might find this interesting. The Microsoft Edge browser, shipping with Windows 10, has removed the nonstandard sizing box that all Internet Explorer versions show when you're editing a field.This was absolutely terrible within the open source editors in mojoPortal, and I don't even know how much time I spent trying to fight this particular legacy "enhancement" to the editing process. It really is a new Microsoft that will forgo backward compatibility and the status quo in favor of cross-browser interoperability.
