Emailing Forms through Mail suddenly not working

[ebaker2]

I email all of my customers invoices and statements every month. I'm using Quickbooks 2011 for Mac and am on the latest update. Today when I attempted to Email Forms when I select one or more invoices I get an error message as follows: "Warning This email application is not supported with this version of QuickBooks."
Mail is working normally, but suddenly QuickBooks thinks it is not supported. Has anyone else experienced this problem or found a solution?

Go to mail>preferences>general and confirm mail is your default e-mail reader. Some users have had issues with third party apps hijacking the default.

Thanks for the suggestion. Chrome had taken over as the default email reader. Changed it back to Mail and everything works!
