IE7 float move left when mouse enter

[BubbaSpanx]

The following code is a "tool bar" of a form that I've coding. Everything works fine but, IE7 not. When mouse enter in a div.btn element, all buttons go 1 or 2 pixels left and p>input.toggle goes to right side over last button.DEMOHTML: <form class="form-file-upload" action="SiGA/pedido/add/" method="post" enctype="multipart/form-data"> <div class="barra-cmd clear"> <div class="btn btn-add bt-adicionar"> <label><span class="icons icon-add"></span> Ad. Imagens</label> <input type="file" name="cmd_adicionar[]" accept="image/*" multiple="multiple" /> </div> <div class="btn btn-send bt-enviar"> <label><span class="icons icon-up"></span> Enviar</label> <input type="submit" name="cmd_enviar" value="http://stackoverflow.com/questions/13844263/Enviar" /> </div> <div class="btn btn-cancel bt-cancelar"> <label><span class="icons icon-cancel"></span> Cancelar</label> <input type="reset" name="cmd_cancelar" value="http://stackoverflow.com/questions/13844263/Cancelar" /> </div> <div class="btn btn-del bt-limpar"> <label><span class="icons icon-clean"></span> Apagar</label> <input type="button" name="cmd_apagar" value="http://stackoverflow.com/questions/13844263/Apagar" /> </div> <p><input type="checkbox" name="cmd_apagar[]" value="" class="toggle" /></p> <div class="btn btn-next bt-finalizar"> <label><span class="icons icon-next"></span> Finalizar pedido</label> <input type="button" name="cmd_fechar" value="http://stackoverflow.com/questions/13844263/Finalizar" /> </div> </div> </form>?CSS:.btn{color:#fff;padding:7.5px 0;overflow:hidden;text-align:center;margin:0 2px;border-radius:5px;border:1px solid #aaa;background-image:url('../imgs/back.png');background-repeat:repeat-x;background-position:left top;}.btn:hover{background-position:left center;}.btn:active{background-position:left bottom;}.btn-add{background-color:#4cb749;}.btn-send{background-color:#3F8DCA;}.btn-cancel{background-color:#fcd209;}.btn-del{background-color:#df2227;}.btn-next{background-color:#910B0E;}.form-file-upload{display:block;} .form-file-upload .barra-cmd>div{float:left;width:150px;} .form-file-upload .barra-cmd label{z-index:1;color:#fff;text-shadow:0 0 15px #000;} .form-file-upload .barra-cmd div input{z-index:3;cursorointer;border-width:0 0 100px 200px;border-style:solid;border-color:transparent;position:absolute;top:0;right:0;margin:0;opacity:0;filter:alpha(opacity=0);} .form-file-upload .barra-cmd>p{margin:5px 0 0 -20px;z-index:4;position:relative;display:block;float:left;} .form-file-upload .barra-cmd .toggle{}
