Just updated to 120b, and after doing so I encountered the following problem -

IQ did not connect to the email account I had specified under Email to IQ, so I had to re-input my email password so that IQ would connect to this account. But after exiting IQ and restarting, I encountered this problem again! Apparently the email password somehow gets "mangled" in 120b, so it has to be manually re-entered every time I exit and restart IQ if I want to connect to this email account. (BTW, it's an Outlook.com account, if that makes any difference, and my IQ database is stored in Dropbox.)

Thanks!
