Well said, OldToad. Thank you. When I saw Mark's advice to "clear the browser's cache," I had to take a long walk to cool off. Good thing I'm retired from my real job. QBO support appears to be nearing worthlessness. The left hand truly does not know what the right is doing. Plus they can't read.

One of the main questions I want answered is why attachments made on 11/6 or before still behave the way I want them to, but more recent ones don't. That is just weird, and points to a malfunction of the program.

If it turns out that this was an intentional change, why in the world would they do that? With the way it has always worked before, I could view the attached file easily, and if I did want to download it I could do so – again, easily – from the new browser tab. So it was win-win. Now I have no choice but to download the file to view it, which is stupid. Dumb, dumb, dumb. And what is the advantage in making this change? Does it eliminate world hunger or something? If the intention is to make me grumpy, mission accomplished.
