I've noticed in mirc 6.14 there's a Really annoying "Feature" , as I'm typing if I've made a mistake I can not move backwards in the text to delete/insert a letter or space without mIRC Eating the next letter in the editbox

Example:
goodevening!
good vening!

it's a real pain.
also, in this new version of mIRC I cannot use CTRL+Del to clear the entire edit box instantly, another inconvenience.
