Sometimes impossible to right click deployments in ConfigMgr 2012 R2 SP1

Lately I've seen that it sometimes is impossible to right click any deployments on a ConfigMgr 2012 R2 SP1 site, if you for an example would like to delete a deployment or just view properties for it.
Does not seem to matter if the site is upgraded or newly installed (from SP2 media).
The resolution.. Close the Console and reopen it again.
