Sometimes a download will not start at all if it is not small, (@ 1MB or greater) it will not download completely, requiring a Pause, then a Retry and/or clearing of the History and a reload of the page. Some downloads take as many a 5-10 such cycles to complete the download. This is also giving one particular secure site, my online college site, Argosy University Online, extreme issues just logging on to the Log-In page, and subsequent pages within the Online Campus.
