Any word on a fix for this yet? That issue appears to have been found
back in version 2006 - however I don't know if Adesk was notified.
I can confirm using Acad 2009 & RD 2009 that after a RD command has been
used, Acad users can not Shift+left click to deselect drawing entities.
pickadd and pickfirst are set to 1.
The "IOptions"(?) > User Preference tab > Mouse Settings option isn't
available in 2009. Is there another location I haven't been able to
locate this option perhaps?
TIA for any clues.
