Bit of a strange one. I added a checkbox to the Duplicate Part and Copy Lines forms within Quote Entry. The checkbox is used to determine whether the user would like to copy the quantities over when the quote or quote lines are copied. The customization checks a UD field that gets set on the company configuration table and sets the initial value of the checkbox based on the value of the UD field. Twice now, once in our development environment and once in our testing environment, the checkbox has gone read only for a period of time for seemingly no reason. It works for a while, then opening it for the first time in a while it is read only for all users, then in the development environment (not in the testing one yet) it became usable again and had no issues since.
Wondering if anyone might know a cause for this or can think of something I may have done wrong or missed. Happy to post the customization code if needed or add screenshots.
