At the start of the Spring soccer season, I had the task of making sure all the practice and game times for my family got posted in my Outlook calendar. With a game every weekend, and two practices during the week (times two teams), an entire season's worth of entries would have taken a long time. The good news is that the soccer league made it easy by enabling an export of the calendar right on their web site. With a simple click of the link to "Download for MS Outlook", they had already set up an export of the data, and all I had to do was import it into Outlook.
Keeping your computer system up-to-date is important, but every once in a while an update can cause a problem. Recently, Internet Explorer 9 caused some trouble with Intuit Merchant Services. In our office, what we saw is that hitting the "submit" button to complete a transaction did nothing at all (no error message, no response). If you clicked away to "cancel", then an error message would appear. Turns out there are several symptoms reported: web pages missing information or not rendering properly, downloads not working, "Page Cannot be Displayed" when accessing known good links, and similar problems.
