We had the similar problem with my colleague. We spent quite amount of time before we found this strange fact. Without myTable prefix it may think, it's some sort of variable rather than field...


>>How is the controlsource for this column set? It should be MyTable.myField If you omit myTable part, you may have this weird effect

>>>I have a 2 column grid on a form that lists the contact names for a student chosen from a combobox. The grid has a textbox in column1 with the contact name and a checkbox in column2 for selection. The recordsource for the grid is a view that contains all contacts for all students. When a student is chosen from the combobox, the view is filtered on that student.

>>>The problem I am encountering, is that sometimes when I go to click the checkbox beside a contact name, it won't let me and a message on the status bar says the control is read-only. This problem is very intermittent.

>>>Any thoughts?
