Help pls

May 19, 2016
I have just purchased the client and was able to login from beta and start dota from there. THe problem is I cant click anything once the game starts, my mouse hovers the options as if im able to click them but doing so does nothing. I cant even shut off by pressing the power button from within the game. Is there anything i have to do to be able to function this client properly?Any help is appriciated
You navigate the menu with the arrow keys. To go back a menu, you can select the option in the window, or hit backspace. To toggle the menu on and off, press insert.
