Trouble Moving Something?

A quickee - A customer just had a problem where he clicks on an object to move it and types in 0,0 as its destination and the block doesn't go anywhere. After some digging we found that the behavior seemed like he was typing in @0,0, indeed he saw this echoed at the command prompt even though he didn't type in an @ sign. He then said he was using Dynamic Input and it worked properly when DI was turned off. Hmmmm. So I went hunting in the SETVARs and found a few pretenders until I hit upon this one:

DYNPICOORDS System Variable

 

Type:	Switch
Saved in:	User-settings
Initial value:	0

Controls whether pointer input uses relative or absolute format for coordinates.

0	Relative
1	Absolute

Weird! He set it to 1 and it worked as he expected, but this is contrary to the way AutoCAD sets it by default. I have no idea why it defaults to 0
