Dynamic Block Problems

Hi,

I have recently, or so I thought, got the hang of dynamic blocks. Most work fine, but some have an annoying error.

After inserting the block, and I add a different scale, then I use the grips to move the block, only one block moves - that is the other dynamic scales of the block remain in the previous location!!!

Any ideas?

Thanks in advance

Don't use grips if you want to move all scale instances; use the move command.
