Last week I upgraded to 2012 SP4 to try to leave the instabilities of SP2 behind, but it has become *LESS* stable.

I have a sketch that I can't rename because it says the name is in use -- (probably by a deleted layout block).

I get warnings that the s'ware can't find files in the swxauto path, but my assemply contains only virtual parts.

I renamed "copy of part" to "part" and the s'ware dies with a fatal error...

Does anyone at corporate care?
