Have now been forced to switch to the new Mail Pro
Have now been forced to switch to the new Mail Pro as received notice that previous version no longer available for use as of end of January 2019.
Have tried Mail Pro several times in the past and switched back since it significantly slows down the response time of keyboard and mouse interface when typing and clicking, causes a significant lag between keystrokes and clicks as well as moving pointer and response to the new location.
Have now been forced to switch to Mail Pro and it still causes the same issues as described above.
Using Windows OS 8.1 and Firefox. Notably, Firefox seems to make Mail and Mail Pro run better/faster and more responsively than when run on Chrome or IE.
