Paul, since you're adding the control at run time, did you set the checkbox visibility to .T.?

I'm probably missing something obvious here or being thickheaded about this, but here's my situation:
I have a standard lookup button class I use all the time that I drop onto a form, set several properties, do a simple query to create a picklist and then it uses CREATEOBJECT to create a simple form from my class library, then it uses ADDOBJECT to add a Grid from the class library and Select/Cancel buttons to the form. After creating the grid, I loop through the fields in the picklist and setup the columns in the grid. I use BINDEVENT to provide the functionality to the click event of each button and the dblclick event of the grid columns. This class has worked perfectly for many years and is easy to use and include whenever I want a simple look up for a single selection from the picklist by the user.
However, today I was trying to add some functionality to the class by adding a checkbox in the first column of the grid to allow users to make multiple selections from the picklist. Adding a 'Sel' field to the query and setting the resulting cursor to READWRITE was easy enough. Displaying the checkbox in the generated grid was also easy. I set the readonly propery for the grid, the column and the checkbox to .f. and everything displays correctly but no matter what I do, when I click on the checkbox, nothing happens.
I've confirmed the cursor is readwrite at runtime. I've monitored readonly properties all the way to the moment the .show() method is called to display the picklist form and they all are .f. until after the .show() method executes. I've traced the code for all the parent elements and can find no other place where any readonly properties are being set to .t.
My question is this: If I'm using ADDOBJECTS and BINDEVENT commands to create this picklist form, do I need to create a procedure specifically for the CLICK event of the checkbox to issue a DODEFAULT() command and then bind that to the Click Event manually or will the checkbox just automatically use the base CLICK event code from the parent class?
I haven't worked with ADDOBJECTS and BINDEVENT commands often (the last time was probably when I wrote the original code for the picklist class I'm trying to modify) and I'm not sure this makes sense, but after a couple of hours failure, I decided to give up and ask for help.
Thanks in advance!
