Copy Class produces locked classes when the source is in a RT target
I'm not sure if this is exactly as described in the title, but that was where I bumped into this. It may also depend on the source class being in a library (not sure).
The class was correctly copied, and I got a new icon prompt and then everything was nicely renamed, but the new (copied) class was added to the My Computer target, which locked both it and the source class (on RT).
The problem was resolved fairly easily by removing the copied class from the project (unlocking the RT side) and then using the Add menu to re-add the lvclass file to the RT target based library.
