Well I think a good idea would be is when you click to install with the sponser another window pops up asking if your sure. That would solve this problem I'm sure. If not, well damn.
Anyways I agree with more options when it comes to the sponser program. You should be able to turn it off and on at will. Really you should be. I would use it sometimes myself. Run it at night and let it display ads. Then just run my supper ad/popup killer and its all good. hehe
Seriously I think if you let the user turn it off and on at will more people will isinstall it and you will make more money. Kinda of a shame thats what its all about but I understand. Personlly if I where you MsgPlus would of been payware a long time ago.
Mabye thats an idea.
