outporb.dll

Dear all,

I tried a matlab program using psychtoolbox routines on win2000 but I had
an error related to the outportb.dll (the program register mouse clicking
and send a signal to the parallel port). The program worked well in win98
and I simply copied the outportb.dll in the computer with win2000. I think
I should get some other .dll for win2000 but I didn't find it in
psychtoolbox web site.
I would appreciate your help if possible.

Thank you in advance,

Antonio.
