In my form Load method, I create a cursor:

CREATE CURSOR USERS (USERNAME C(30), LOCK L, userid n(5,0), sendmsg L)

I have a grid on my form that is bound to this cursor. The grid has 3 columns, two of which are using checkbox controls as their Current Control value. The checkbox columns both have sparse = .F.. Both checkbox columns have ReadOnly = .F. while the last column (with the default textbox control and sparse = .T.) has ReadOnly = .T.. The grid itself is set to ReadOnly = .F.

When I run my form, the checkboxes appear correctly (much rejoicing) but I'm not able to check/uncheck either of the checkboxes in any of the rows.

What do I need to do to be able to allow the checkboxes to be checked/unchecked?

Thanks for your help.
