RE: Grid Control: Check box state reverse reported?

Dan,

It is not a timing problem. What is happening is that EGW_CLICK is sent 
when you press the mouse button down, but the value in the checkbox only 
changes when the mouse button comes up (this is the default behaviour 
for checkboxes I believe).  I had been meaning to change this in the 
next release to add two messages EGW_LEFTBUTTONDOWN and EGW_LEFTBUTTONUP 
to cope with this.  As it is a minor change I will try and do this in 
the next day or so and post the change to Rob.  Can't think of a 
workaround in the meantime I am afraid...

Regards,

Phil
