Ok so, i have been having this problem for ages...
when i type: "test test test"
in the mirc editbox, when i type in the editbox, and then try to insert text at various positions within, (sometimes) it over-rides text at position X with what i type... also removes text after position X...
I dont know if this is a mIRC bug or Windows10 bug. So far, i only see it in mIRC editbox.
It's been annoying me for ages!
Any help is most appreciated!
