Ailan

All other design layers are turned off, Show/Snap/Modify others is on, but various parts of my drawing are grey. I cannot select these or edit them in any way. I saved a new version of the file and they appear the same way. Some of the objects were originally part of a group, and I don't think they were ungrouped before this problem started. In my 12 years of using the program I haven't experienced this. I'd love some help.
