mintty will not accept the letter "e"

[Ken Reek]

Hi, all.

All of the sudden, mintty won't accept a lower case "e" -- it just dings
when I try to type one. Upper case "E" is fine, as are all the other
letters. I'm no mintty expert, but I think the e key might have been
remapped somehow.

Any ideas on how I can fix this? I've killed mintty and started it again,
and also rebooted my machine, to no avail. I'm on Windows 10. Thanks for any
help!
