incompatibility of an ocx in visio that works in access sgrid

[Brady Guy]

I am tryiing to use www.vbaccelerator.com 's sgrid control in visio. This is
a free opensource type control. It seems to work fine in access but in visio
I get a runtime error that corrupts my form. In visio 2003 if I create a new
document go into VB create a new form drop the sgrid control on it then run
the form, then close the form I get a run time error type mis match. If I
do the same thing Access no problem. There is no code behind the control
just putting it on the form displaying the form and closing produces the
error. It also trashes the form. If you try and double click on the form in
VB in design mode you get a run time error and it will not display the form.

Any thoughts on what might be going on here?

Thanks
