As of this morning, the ZohoMail Windows app keeps freezing up. Shutting it down and re-opening it doesn't help, and I have to restart my computer in order to get it working again - only to have to freeze up again a short while later!

I've been using the app for a couple of years now and never had any issues with it until now.

Has anyone else been experiencing this, or got any ideas what the problem might be?

Thanks!
