Hi there, @NonProfitTreasurer.
In QuickBooks, as mentioned by my colleague above, the column adjustments will revert to their original width when logging out or changing tabs.
In the meantime, you can follow the workaround suggested above so your adjusted columns won't revert back.
Don't worry, I'll also pass this along to our engineers so they can take a look at it.
Please feel free to leave a comment below if you have any other questions.
