I have followed these directions and it doesn't work. When I switch accounts, it reverts to the default columns. Is there a place to change the default?
Sorry, there's no "global default" for all banking registers. After you have set the columns for the register of one account type, you can use my instructions to copy the settings of one account register, e.g., a 1-line Checking register, to all other 1-line Checking registers in your data file. If you need to change settings for other account types repeat the process, e.g., in a 1-line Savings register. Quicken will remember the settings across sessions.
If that doesn't work for you or if you run into problems, please provide more details. Screen image snapshots might be helpful to determine the nature of the problem.
