Frequent (and normal) "Connecting to..." errors obtrusively popping up. - Google Apps

Google Apps, free edition, has always thrown frequent connection errors, probably when an email clients tries to connect multiple times or too frequently. It happened with outlook, too – often when I tried to delete several emails quickly. The error messages could be safely ignored. It will try again in a minute and be fine.
But the way that em client throws these errors, it interrupts what I am doing, sometimes, I think, grabbing the active window so that the last bit of typing I was doing in another email or elsewhere was not in the right window.

I need to be able to suppress the error messages so they don’t pop up and interrupt – or just stay hidden so I can see them if I need to.

Great work on EM Client! Brilliant.

EM Client 6.0 (there’s no check box in the right column for that)

Hi, try to install this version http://www.emclient.com/dist/v6.0.197… and tell me if that has worked.
