Came across an Updater for Canon Digital Cameras ZoomBrowser to version 5.2.1 follow the link and click on software under drivers and software. Size 39.5mb. This new version looks much better and faster. But I had a problem running the update till I ran Winzip and extracted the files and then I ran setup.exe from the \ZOOMBRSR\ENGLISH directory. This ZoomBrowser seems to be common for most Canon Digital Cameras that use it.
