I have my furniture blocks..been using for years.....when I open a pre-existing block drawing, I can edit everything using the properties box except for my "value" attribute which is my item number...I can edit all the other att's, shapes and text..just not that one...when I double click on it, it opens the properties box and still won't let me change it..the box is not greyed out...just doesn't let me in, so I have to open it in 2005 to edit it.........what am I missing?!??!?!?!??
