Why do I get an error message when trying to send an email in my gmail account?

[AC Question]

When in gmail, I try to an email and it says

When in GMAIL, I try to open an email and it says " NO MORE WINDOWS AVAILABLE." & "THE MAXIMUM AMOUNT OF WINDOWS (16) IS OPEN. CLOSE SOME WINDOWS AND TRY AGAIN. " It's got to be my gmail because my Chrome browser only has 2 open. This has become very frustrating - I can't even read emails.! I've tried for 2 days.! Please help.!!
