Can't edit block Tool Pallete properties

[b.mossman]

I have a named block in my current dwg that I right clicked and dragged to a tool palette. When I right click on the block properties to change the Auxillary scale, layer, etc..., all of the fields are grayed out & I can't enter data. I can however edit existing block properties that are installed with acad. Is there a setting that controls this?

C3D uses a insertion conversion when inserting blocks. This allows multiple units to be used. Check help on the command "insunits", I'm not sure if this is causing your problem, but you may want to set your insunits to 0 ...= unitless.... then insert it and try it again.

I've made several attempts, but I can't seem to create the same issue on my own machine.

I changed insunits to 0 & it didn't affect it.
I can change the properties on the standard acad vlocks on the tool palette, but for some reason when I drag a block that I created onto the tool palette the fields are grayed out and are non-selectable. I'll try the same dwg on a different machine on Monday. Thanks for the help.
