After this thread
I tested a while to find a way to replicate some of my errors.
I have found a sequence of Actions to force the corrupting of r# caches in build 227
But it is not so easy to put it into a bug report, and you need minimum 3 different projects for testing.
but you can contact me via ICQ 1603858 or msn messanger via my forum email address.
if this is not possible pleas tell me, then i will try to create a test project, write it down a tutorial
