Running the 32bit portable version on Windows 10 and after update to 52.1.1 email is extremely slow to load each message, clicking to reply or even write new emails takes a long time to load, 10-20 seconds when it used to be immediate. I've rebooted, not sure what else to try except maybe a roll back but not so sure how to go about it. Any help is appreciated.
