Glitch when selecting colors

 I am experiencing a glitch that I believe is hurting my sales that I cant seem to figure out. I use the fancy product designer so customers can create "color proofs" of pre-designed products. When I select which color to choose say it is "Color 1" when i hover over the colors to select a color, the page will jump to the top of the page and wont let me choose my color. The only way I have found to remedy this, is to zoom out on the page far enough where the scroll bar will be at the top and when i select a color it wont be able to jump. Obviously this isn't something most people have the patience to figure out. Does anyone have any suggestions?
