Win7 x64 shows the start orb after update (Start Killer 3.2)

Recently, there was a windows update that fixed something like a bug with 999 entries in jump list or something, it updated explorer.exe I guess, and now when I press the windows button on the keyboard the start orb unhides and I have to restart start killer for it to hide again.

I've installed this update, but I can't to reproduce the bug

Theoretically, anti-virus/malware software can block the start killer because it inject code into the explorer. Maybe here is the problem?

I use MSE, and it hadn't been a problem before. I also have this skin installed, maybe that's the case.
