I can't remember if it happened on multiple dbs.  I am still in the testing stage for releasing my app with Valentina 5.3.4.  

I know it is unconventional to make schema changes to a db and also upgrade the db engine, but this is a freeware app.  I'm updating the schema on a number of tables.  I found that if I changed the order of updating the tables, this problem went away.

5.x

No problem with Valentina Studio. I definitely remember trying that, but not on Windows - only the Mac.

Let me try and reproduce the problem and if I can, I'll submit a Mantis report.
