D8 Hanging

3 time recently I have hd Dreamweaver 8 hang when I've been deleting CSS styles
in the panel. I get an error about javascript exceptions (did'nt catch it).
Bits of it still twitch because I can go between design andcode views but not
use them. Have to kill it and restart whence the proble dissappears. Anyone
else experienced this?

PS How do I get to receive emails when a response is posted?
