MacOS Sonoma updates Tabs which now do not display correctly in Big Business 14. As pictured, the Name of the tab (Customer) appears blank when that Tab is selected.
Big Business 14 will be updated to fix this problem several weeks after macOS Sonoma is released, perhaps, and may entail updating Big Business 14 Server and Clients, too.
This problem is fixed in Big Business 14.61 which requires updating Big Business Clients along with Big Business Server.
