mala's stopped loading on boot up??????

[Mr Wilson]

i've been running mala frontend its all been working fine turn on pc it loads the windows welcome screen then straight into mala
then last night turned it on you get the welcome screen and music then the music  just starts stuttering and it goes to the desktop???
the way i've had it booting was by changing the shell in regedit to c:\mala.exe and this has worked fine up until last night

when i change the shell back to explorer.exe and restart it boots fine straight to the desktop with out any stuttering??
has any one got any ideas whats causing this
Cheers

right uninstalled everything mame,mala etc and reinstalled it started it up ( i was sitting downstairs with pc plugged into a old monitor) and it booted straight to mala turned it off took it up stairs put it in my cab booted up same prop??? could it be my trackball that i got the other day conflicting with something i had it plugged into a usb port but changed it to a ps2 but the same thing happens?( but it happens when the trackball and my cp aren't plugged in??)
its starting to do my head in

try removing all usb devices from windows device in cotrol panel. unplug them all. then turn off pc. plug all back in and turn on again. dont pull or swap any USB stuff over again if it works.




does mala start from desktop?
