Version 8.7.1 – noticed a minor bug while altering a table – if I first select a bool type, and tab across to the next field, but go back to change it to a decimal, the unsigned checkbox remains disabled. The only workaround is to delete the entire row and recreate it, ensuring to select the correct type the first time.
Sorry for filing a third bug report – I hope this helps and makes the product better, because it truly is the best out there.
