A few minutes ago I encountered a little difficulty while I was surfing the forum. Now if you notice , the karma giving buttons  are on the post page and actually take effect immediately it is hit. Due to this I clicked the [+karma] button accidentally and unknowingly to me via my PC cursor. I had already finished reading the post and was about proceeding to another page when I noticed the reload on my current page and the karma had increased by an additional one which I didn't want to give on that particular post. 

Now my suggestion is quite simple i am of the opinion that both the +Karma and -Karma open up a new page with a prompt message when hit. Probably something like this;



This will prevent members from accidentally giving [+Karma] or [-Karma]
