flipper_MD,

Are you a doctor, cause I've got this pain in my ...
Oh ... you're probably a porpoise doctor

Ummm no, I don't really see a reason for problems disabling at that point.

The closest thing to a problem I can see is that the GrabBkLt command will take over 3ms to display the LCD data ... 2ms for the command and 20+ chars at 50us delay = 1ms.

3ms by itself shouldn't be a problem, and it should only happen infrequently, but it's the closest thing to a problem I can see at first glance.

What are the symptoms?
