"ghost dots"
Could they be nodes
If so make sure that you have then selected on your ONSNAP settings
Get a nice clean, slightly moist cotton cloth and wipe your entire screen until it is clean.
Have you tried putting a piece of black electrical tape over the ghost dots? It ain't pretty but I'm all about real world solutions.
Are you talking about nodes?
Maybe try this?
Command: Erase
Command: All
then ??deselect? the stuff you don??t want to erase
Can you explode the offending dots/nodes and then delete them?
If the block you erased from the drawing is still defined in the drawing... try the PURGE command to jettison the offending block definition to rid yourself of the annoyance.
Good luck.
I sent my Template DWG to Carlson and this was their response.
"There were zero-sized text entities in the drawing".
Georgia IDIOT, I made that up.
