Bookmarklet doesn't work when placed next to address bar

Hi

I have problem with bookmarklet from regex.info/exif.cgi (it only displays when you set Opera to "Mask as Firefox" in Site Preferences")

javascript:var form=document.createElement("form");form.action="http:"+"//regex"+".info/exif.cgi";form.method="get";form.target="exif";var O=document.createElement("input");O.type="hidden";O.name="b";O.value=3;form.appendChild(O);O=document.createElement("input");O.type="hidden";O.name="referer";O.value=document.location;form.appendChild(O);O=null;function f1(obj){if(obj.links.length>0){var R=/.(jpe?g|nef|raw|tiff)$/i;var count=0;var url;for(i=0;i<obj.links.length;i++){if(R.test(obj.links[i].href)){count++;url=obj.links[i].href}}if(count==1){var O=document.createElement("input");O.type="hidden";O.name="imgurl";O.value=url;return O;}}return null;}function f2(obj){if(obj.images.length==1){var O=obj.createElement("input");O.type="hidden";O.name="imgurl";O.value=obj.images[0].src;return O;}return null;}function f3(obj){if(obj.images.length>=1){var img;var max=0;for(i=0;i<obj.images.length;i++){size=obj.images[i].width*obj.images[i].height;if(size>max){max=size;img=obj.images[i];}}return img;}return null;}function f4(obj){var img=f3(obj);if(img){O=obj.createElement("input");O.type="hidden";O.name="imgurl";O.value=img.src;return O;}return null;}function f5(FRAMES){for(var fr=0;O==null&&fr<FRAMES.length;fr++){try{var O=f1(FRAMES[fr].document);if(O)return O;}catch(er){}}var max=0;var img;for(var fr=0;O==null&&fr<FRAMES.length;fr++){try{var I=f3(FRAMES.document);if(I&&I.width*I.height>max){img=I;max=I.width*I.height;}}catch(er){}if(img){O=obj.createElement("input");O.type="hidden";O.name="imgurl";O.value=img.src;return O;}}return null}var O=f1(document);if(!O)O=f2(document);if(!O)O=f4(document);if(!O)O=f5(frames);if(O){form.appendChild(O);document.body.appendChild(form);form.submit();}else{alert("Sorry,I could not find out an image to report on");}

It does work OK from bookmarks/ favorites bar but when moved next to adress bar (holding Shift) it will display "OK" tooltip when hovered and do nothing when clicked... ???
