edit block in place 2015

Hi have been using autocad 2015 now for over a week and havent run into any problems....until i started to "edit a block in place" today.  first i tred to edit a dynamic block in place and i can edit it but as soon as i hit save, i get locked up.  cant reopen the drawing, cant recover the drawing. have to open autocad and open the drawing before i tried that edit.  i thought maybe the problem was trying to edit a dynamic block, but then when i tried to "edit in place" a regular block the same thing happened.  I hate editing the block in the block editor which is why i right click and use "edit block in place".

anyone else had this problem?
