I'm having the above issue with RKLauncher. No recent changes or installs at all, just my normal gaming, browsing, iTunes radio, really nothing out of the ordinary. This morning I started up and the dock didn't show. It's still running as a process (according to taskmgr) but nothing happens. If I run the executable again I get TWO instances of RKLauncher but still no dock. I can end the process, no problems. It's been working fine for ages (like 2 years kind of ages) and now suddenly this. Can someone advise please? Thank you, Nicholas.
