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?
