Another one on the MS Money front – the default for Money 2005 is one categories field that has sub categories delimited by a colon. One cool thing is if you start typing the name of a sub category, it will resolve it. But what if you liked the old style dual list? Never fear, you can bring it back.
Detailed in this KB article, you basically need to create a DWORD value in the HKCU\Software\Microsoft\Money\14.0 key called “UseDualCatMode” and set it to 1.
Obviously, if your are mucking with the registry, please know what you are doing.
