We are not version specific with Google Chrome, only that it is supported. However, with that said, per Google Chrome, AFTER version 44 they no longer support applets. For Sourcing that would only affect the Auction Monitor. We would recommend you use the Bidding Page of the Auction as that page is the replacement for Auction Monitor.
The PAM has the supported browsers as well you can review this blog from our Product Management team.
