For some reason when I play myth recently my input has been screwing up. When I hold down a button and click (as in shift, control or alt typically), it generally accepts the first click properly but then when I click again it typically doesn't recognize the click unless i let go of the button I've been holding down. If i continue to click a bunch of times it makes an error sound like I'm pressing too many buttons on the keyboard. It makes one sound for every click I do. I tried switching out the keyboard to no avail so I'm not sure whats going on. Anyone have any ideas whats going on or what I can try to fix it? I'm on WinXP for the record.
When I have a similar issues it means my keyboard's batteries are low. You do have the latest update right? You could always reinstall Myth and reupdate it. Sometimes that solves any issue you may recently had but didn't before.
