F1 focussing character

Has an update been put in place with ensage that makes F1 focus character if double pressed? 'cos it wasn't like this a week or two ago, none of the scripts have F1 set to focus char nor do my hotkeys have it but it still keeps on doing it...

F1 has been the default command for focus since Warcraft 3 (maybe earlier?), backup your dota config and try resetting the controls to default in dota's settings.

I never noticed it doing it until this week cos that's what I have always had combo key on and if I press it twice to quickly it changes view and ends up messing up the combo.

I can't see anywhere to disable it in dota settings, I have always had focus char set to a different key and not sure why it would keep a default key when a different one has been set. It could just be a bug and a reset of settings to default and change again may fix I'll try that tonight
