I've been picking up fill, pen, and text attributes mostly.
After using the dimension tool inside a symbol, when I try to use the eyedropper tool to grab the attributes of other dimension lines, the programs crashes.
I can replicate this consistently following the steps above.
The work around is I just hit save before using the eyedropper, quit the program, then open it again and use the eyedropper once. Every time after the first will crash.
