` key

alrighty... i found the issue (to an extent):

to switch through the languages (while using the language bar), the grave accent was used (i disabled it in the hotkeys settings for the language bar). though, however, i have not found a way to disable ` + a/o to make àò in mIRC. ` works just fine in Firefox though. >_<

There's a workaround that includes some extra effort, if you want to use that sign (`) in mIrc: tapping the key two times produces ``, two times the grave (first one does nothing, waiting second keystroke and when second character is not a letter as it expected, you'll see two graves printed on the screen). Then backspace to eliminate the second one.

Same with acute and tilde, tapping (´) two times gives ´´ and tapping (~) two times gives ~~.

Confusing and complicated
