Look like a over loaded gray out condition of use of memory, alot of features disapper when memory hits limits
Make two copy skeckup 8 one with no plugins (in plugin folder) for the layout, and the other (with plugins) for editing objects. (to layout)
Start the object sketchup first,
Then open layout sketchup.
Do your work:
When done close layout sketchup first,
Then close object sketchup last
also
A Fix for some startup Sketchup splats:
Clean out the reg of google sketchup 8 toolbars useing registry editor and wordpad then open only the plugins you need.
You may had a 1000 listed witch loads to ram memory evey time it loads often cause sketchup to splat.
(hint) keep a copy of of google sketchup 8 reg save to fix problems later
