I belove I accenditally stumbled upon a solution for x-notifier not working suddenly with chrome.
First I tried X-notifier NEO after my trusty x-notifier origina crispy flacvor stopped working. It would not work. (I run Chrome, windows 7 ultimate)
So I gave up on that and I added "Notifier for Gmail 0.7.4" in an attempt to get my multiple mailboxes in order, but it functioned poorly. Notifier for gmail can be found here: https://goo.gl/imJPmA
I'll just note that, in Chrome, when I first start my browser and X-Notifier (v3 or v4) first checks for new mail... it only checks my primary Gmail and leaves my second and third accounts unchecked (as well as my mail.com accounts). All my other accounts are checked fine. HOWEVER... once the check interval time elapses, ALL my accounts are checked from then on (including Gmail and mail.com accounts). I don't know why, and it's not a major problem for me to waste time fussing over.
4.0.2 does not work for me at all. Single click does not give me a dropdown to check mails individually, just checks them again. Does not notify me of new mails. I just want to go back to 3.5.23, but can't find a chrome version anywhere, not even a .crx.
