Thanks for the replies, guys.
Stephen, I'll assume that first comment was tongue in cheek, so I won't bother you with my opinions on other packages, LOL.
Cal, that's a good point about the upside of having a static version. I had not heard of (or didn't recall) the dll patch you mentioned ... doing a quick read online, it appears that it was created to help with Win 8, which I never used (I went straight from 7 to 10, and now 11), but perhaps at some point I picked up the new dll, either intentionally or unwittingly.
I really should've created a note document to list the "quirks" to which I referred, but I guess I'm typically in the mode of accomplishing the task at hand and don't stop to document the issues I bump into (I would make a lousy software tester, I guess). But I can offer one example that I can recall because I have to do a manual workaround every month: after moving from my old Win10 PC (which was bought as a Win7 PC and then later moved straight to 10) to my new Win11 PC a year ago, I noted that I am now unable to update my mortgage payment details. I don't recall the exact error that I'm getting, but after spending too much time trying to figure it out, and since I only have a few payments left, I simply reverted to letting the payment post each month and then I update the escrow amount.
I admit that there are a lot of potential variables here ... for example, I can't say for sure that the version I downloaded and installed on this PC (17.0.150.3817) is exactly the same as the one I was running on my old PC, which had been running on that PC since I bought it over 15 years ago. So I guess it's not 100% confirmed that it's purely a Win11 thing.
The other thing with Money is how slow it can get when it has a lot of data ... it's better on my new PC, but still not great. (Side note: I'm familiar with the tip about replacing rather than editing entries in the Bills summary.)
So, at the end of the day, count me as a longtime fan, but I'm afraid I view Money as a tool and not a hobby, so after 26 years I think it's time for a new tool. Thanks again for your replies.
