I have a small problem with the 'About This Mac' menu.
When I click at 'About This Mac' no information is shown but a restart occurs.
I have installed 'SL_10.6.6i_by_Hazard' and upgraded it to 10.6.8 ... that worked OK
I have installed MaxOSX as a virtual machine in Virtualbox 4.1.8 (Linux host).
When I look at the files in:

/System/Library/CoreServices/Installer.app/Contents/Resources/defaultBackground.tiff
/System/Library/CoreServices/loginwindow.app/Contents/MacOSX.tif
/System/Library/CoreServices/loginwindow.app/Contents/MacOSXServer.tif
/System/Library/CoreServices/loginwindow.app/Contents/Resources/English.lproj/AboutThisMac.nib/

they are the Hazard logo with the gas-mask.
What could be the problem ... have Googled but no success ... also posted the problem to some forums ... but no answers so far.
Appreciate all help
