[SOLVED] Need fix for popping hover over button?

Need fix for popping hover over button?

I need help to fix the error of my smiley button and pops when i hover over (see example below). I think the problem is related within .chatbox / form field or hover smiley. It could also be related to the div style min/max-width details etc.

Any suggestions or examples would be very grateful here. Thx stewy

   position: relative;
}
.hover img{
   position: absolute;
}
