fork is emulated barely enough for certain use cases. Sharing resources across that emulation, such as Win32::OLE objects, is not implemented and thus does not work. But as you only want to run two programs in parallel anyway, just use system:

system('start "Program 1" perl -w program1.pl') == 0
    or die "Couldn't launch program1: $!/$?";
system('start "Program 2" perl -w program2.pl')
    or die "Couldn't launch program2: $!/$?";

Alternatively, you can use the following form:

system(1,"perl -w program1.pl")
    or die "Couldn't launch program1: $!/$?";

[download]

to launch a program without waiting for it.

Maybe you want to look at WWW::Mechanize and/or WWW::Mechanize::Firefox, which give you more control over what happens?
