Cal,
Weird behavior in the Account Transactions reports has been around for awhile. In case it might be useful, I've attached my crib sheet of
"Weird MSMoney Stuff that Is Not Fixed with Money Sunset"
Item #1 is an issue with dates that are off by a month in the "Account Transactions" report.
Also note item #12, which I encountered just last week. If a report uses "All Payees" it's important to tick the "All Payees" box every time the report is run. Businesses that make slight changes to the payee name for every transaction (looking at you, Amazon) generate constant updates to the payee list. These won't be picked up in, for example, a "Favorite" report that you set up and saved a few weeks ago unless you select "Customize" and re-select "All Payees" before you run it.
This is certainly not a full list of fixes and improvements to MSMoney that would be really nice to have. Dick Watson tracked many issues over the years and, sadly, very few of them were implemented.
