XN 4.1.8 Chrome doing strange things

I'm having a lot of trouble with XN right now, and I'm wondering if it's XN or Google

1) When I try to do a manual check, it signs me out of all my emails and then I'm forced to sign into all of them individually all over again. 

2) When I try to check an individual gmail account from the drop-down menu, it takes me to another email, usually my default. 

3) Gmail doesn't seem to be accepting the XN logins, as I always get the login page asking for my password.

Is it just me?

Google supports access to multiple accounts at the same time... however, when using X-Notifier, you have to open those accounts from the X-Notifier drop-down menu or else the session tabs get confused.
Always open your gmail tabs from the X-Notifier drop-down list... that keeps mine straight.  
As far as I can tell, my gmails are working normally with 4.1.8 on 64 bit Chrome 64.0.3282.140

I've just noticed X-n 4.1.8 on Chrome not checking my 2nd Gmail account. If I click on my 2nd account in the drop down, it takes me to my 1st Gmail account. I have to log out of that and log in under my 2nd account. I've got multiple Outlook, Yahoo, and Husmail accounts as well and the only other emails that has an issue is Hushmail but it seems there's nothing to be done from http://xnotifier.tobwithu.com/dp/node/3641. 

Well, I have X-N 4.1.8 and Chrome Version 64.0.3282.186 (Official Build) (64-bit)....  and I am not having a problem with checking three gmail accounts or opening them up in multiple tabs at the same time.  Perhaps you could try clearing the browser cache and cookies.

I'm glad it works for you RpD but it doesn't for me.

I've got Chrome set to clear history, cookies, cache, passwords, site preferences on close AND I use CCleaner at least twice a week.

Like I said above, Gmail and Hushmail are the only emails effected. My Outlook (x3) and Yahoo (x2) work fine.

I forgot to mention that the link you supplied above, unfortunately included the period, etc... so it doesn't work.... http://xnotifier.tobwithu.com/dp/node/3641.%C2%A0
However, this part does:  http://xnotifier.tobwithu.com/dp/node/3641

Yes, Hushmail and others do not support multiple logins at the same time from the same client, so you have to use one tab per provider accessing one account... except... gmail, because Google does support multiple account access from the same email client at the same time. So X-Notifier can open multiple tabs, each with a different gmail account.  I'm just going over this for others reading here.

As for your gmail problem... were multiple gmail accounts/tabs working previously?  And then stopped? Or did you just install X-Notifier, or just update it?  Or just start clearing/cleaning/wiping all settings?  Perhaps you should make an exception for X-Notifier cookies or at least the gmail accounts.
