I have downloaded this a few days ago and after playing for a while it started trying to close asking me if I wanted to exit I kept saying no but it kept saying do you want to exit is there a virus or is that just a bug?

No I was working on some random thing to blow up and it kept acting as if I hit it

I wasn't using the keyboard! I use only my mouse cause "I" personally have no use for the keyboard while playing Powder Toy

Dude I can garuntee you none of my keys stick or even resist moving the slightest bit. And zoom is use less The only thing I want bigger is the damn screen size. It's too tiny and small.

I am redownloading it because last time it may have been caused by my repeated hitting of the close button although the closing attempts were a few minutes after the repeated close pressings.
