block won't load into empty tool palette

[Cadman1957]

Good morning,

 

 

I've created quite a number of tool palettes, including nine palette groups, and everything has been working great. Now, of a sudden, I can't drag and drop any type of entity into an new, empty palette. I can still load whatever I want into an existing one, but nothing into a new one. I've created the palette both through the palette itself and through the adcenter, but nothing works.

Anyone have thoughts?

 

 

Thanks,

 

 

Tom
