ShowCursor has minor problem

1
After solving the video playback problem for lasted PTB, I switched to the latest version under Windows for real experiments.

However, I have a minor problem with ShowCursor. After a screen is open and HideCursor, the command ShowCursor itself won't show the cursor. If I try ShowCursor(0), it works fine. This is not big deal, but it would be nice if it behaves consistently as early versions.

Info:
PTB 3.0.10
Matlab 2010b/2012b (32bit), 2011a(64bit)
WinXP 32bit, Win7 64bit

Thanks.
