I also am having an issue.
I am running 10.7.3 however.
I installed InDesign CS6 (version 8.0) and if I have all my plugins running it will crash EVERY TIME on start-up.
However, I systematically removed all plugins and found that the plugin that causes the problems are:
PMPACK (completel doesn't work)
UI (lags the computer, very slow) - but if I remove UI I have NO tools.
Any ideas or suggestions?
