Accounts with foreign names... Ö Ä Å

I'd be glad to help you add customers and vendors with non-US letters, @Flyingkiwi. 

To start, let's resort lists in QuickBooks Desktop. This will fix any odd behavior in your master names list. 

Here's how:

1. From the Edit menu, select Find.
2. Select the Advanced tab.
3. From the Filter list, select Name.
4. Select the Name ▼ dropdown, then press Ctrl+L on your keyboard.
5. Select the Include Inactive checkbox. If it's grayed out, there are no inactive names.
6. Select the Name ▼ dropdown, then select Re-sort List.
7. Select OK.
8. Close and reopen your company file.
