Hey guys, I've now done about 10 painless upgrades to Windows 10 on various machines running Win 7 and 8.1, 32 and 64-bit, but on my main machine I cannot get the calendar popup appearing when I left-click on the date&time in the task bar. Left click on other task bar icons works as expected, just not on date&time. It's not end-of-the-world stuff, but it is bloody annoying, as I am often trying to quick access the calendar. So far, I haven't been able to find anything useful in Google searches. Does anyone have any clues on how to fix this?
