Hi David,

I know it's a very old thread, but we discovered another bug, which my colleague claimed we had from VFP3.0

If you put a subclassed checkbox in a grid column, set sparse property to false, set readonly to false for grid and the column and try to click on the checkbox, it creates some weird visual effect, like it tries to click itself automatically. It doesn't seem to be a case with VFP native checkbox control.

Could you please replicate this behavior?

Thanks.
