I am currently running commercial Postbooks Xtuple 4.11.2 on Ubuntu 18.04/PostgreSQL 10.1. Works well. I have tried twice to update to 4.12.1 in preparation for moving to the Enterprise addition. The update went smoothly with no warnings or errors. When I run the new 4.12.1 client it opens normally but all is not well. I seemed to have somehow lost the desktop. No workflow Icons in the middle or menus down the left side, just a grey screen. The commands/icons along the top are there. Some work normally but clicking on System/Preferences for instance crashes the client. Also using the old 4.11.2 client brings the desktop back. Anyone have any idea as to what went wrong with the update?
