okay well, this post would be in the wrong section to start with(should've posted in the mirc help section) but, whos complaining :tongue:.
there could be a couple things to choose from here, could be a bad copy of mirc, in which case you should re-download and try the install again. or couple be a script causing conflict. or even yet, your keyboard could be sticking??...
in anyacase, i would first reccomend to unload any scripts you may have running .
if the problem is still there, then perhaps you should get a new copy of mirc and do another install.
lastly, may check you keyboard ??
