First experiences:
1. 12.0.55 installed fine after IE7 B3 was reinstalled, as mentioned in a seperate thread. Upgraded to 12.0.56 and although there were no installation errors, it wouldn't show itsellf when open, even though it was listed in open processes. True Launch Bar plug-in Media Control reported that MC was not open. Tried the following steps to resolve:
Uninstalled, left registry entries, reinstalled: same results
Uninstalled 11.1 and 12, reinstalled 12: same results
Uninstalled 12 including registry entries, reinstalled: successful installation and MC became visible when opened.
2. Library --> restore --> Detail view: fails to paint appropriately.

3. CPU usage varies from 1% to 98% w/o any obvious reason. I haven't performed any tasks within MC yet, with the exception of enabling and disabling "watch folder" and scrolling through library. When it was building thumbnail icons the usage was high, but I haven't been able to reproduce it.

Closing MC does not release the Content Index Service, which has to be manually killed.

For reference this is my CPU usage with MC closed.
