Hi, I'm not sure if anyone else is experience the same type of issue.
But in recent months my Google Chrome Helper is constantly consumer between 80 - 100% of the CPU only when I have Zoho CRM running in the web browser.
Every instance of Zoho CRM I am running (so say 3 tabs), each will be consuming this much CPU.
I'm using a Mac Sierra with Google Chrome Version 67.0.3396.62 (latest)
I used to be able to run 5 - 6 instances of Zoho CRM with no issue.
