New Email -- Slow typing and lock ups!

When typing in an email that is being replied to, I’m typing faster than eM Client can keep up. Characters are oftentimes appearing after the keys are hit. This makes the characters appear that they are being cached. Worse, this slowness is periodically locking-up eM Client for 15 to 30 seconds.

Nothing has changed with my PC that I’m aware of. All other software is running fine.

Version of eM Client is: 8.2.1659 (845a639)
The PC is a Windows 10 HP Laptop; Intel i7 7500U CPU, 16gb RAM and a SSD.

That type of thing is normally when something in eg: resident memory is interferring with the program or Windows has for whatever reason maybe run out of ram and maybe gone into virtual ram which is slow.

Usually a reboot of the computer will clear anything like that.
