In the schematic and PCB editors, if you select, say, 40 of the same part and choose Update From Library, the modal window that opens is extremely slow. Clicking the 'select all' checkbox in the top left corner hangs the browser for 30+ seconds. During that time, Chrome displays 'webpage not responding' warnings. If you wait, it will eventually work. Even selections of around 20 of the same part will cause this hanging behaviour. Please let me know if you would like any further details. All the best, Dax Liniere.
