Game occasionaly crashes when I am searching in MM, or when I ALT+TAB the game. It happened about 5-6 times so far.
Problem with the game opening when you ALT+TAB it. I think there should be some hot fix if possible wih this issue, because as you know many of proffesional dota players use multiple programs while playing and thus use ALT+TAB very often. For example, IRC channel, Skype, Mumble, playdota/gg.net/TL forums etc.. I realise that ALT tab is a huge problem with most of the VALVe games, because i have experianced it with TF2, HALFLIFE2, Left4dead, etc... I hope they can fix it so it can be a lot faster then it is atm.
