This is an inconsistent problem that started at least a week or so ago, but it's now happening about 75% of the time. Here's an example:
- I have my Windows apps showing in the Dock
- I am in FireFox and want to check email
- I tap the Outlook icon. Nothing happens.
- With the two-finger tap, I can bring up a list of what's already open in Outlook and tap on one of those items to get it to open
- I want to return to Firefox. I tap on that icon. Nothing happens.
- And so on, all day long.
