Par, Wx oddities, win2k

BUU has asked for the wisdom of the Perl Monks concerning the following question:

I'm running activestate perl 5.8 on windows2000. I installed PAR and Wx via the ppm.bat utility. They both install fine and work fine, I.e. my test Wx script:

#!/usr/bin/perl -w
use strict;
use Wx;

###########################################################
#
# Define our HelloWorld class that extends Wx::App
#
package HelloWorld;

use base qw(Wx::App);   # Inherit from Wx::App

sub OnInit
# Every application has its own OnInit method that will
# be called when the constructor is called.
{
   my $self = shift;
   my $frame = Wx::Frame->new( undef,         # Parent window
                               -1,            # Window id
                               'Hello World', # Title
                               [1,1],         # position X, Y
                               [200, 150]     # size X, Y
                             );
  $self->SetTopWindow($frame);    # Define the toplevel window
  $frame->Show(1);                # Show the frame
}

###########################################################
#
# The main program
#
package main;

my $wxobj = HelloWorld->new(); # New HelloWorld application
$wxobj->MainLoop;

works fine when I run it from the command line, "perl wxtest.pl". I get my nice window and stuff. I have another simple test script, test.pl which just contains print "hi". Then I did pp -o test.exe test.pl. The produced test.exe works fine and prints "hi".

However when I run pp wxtest.pl; I get a nice executable named 'a.exe', but when I try to run it from the command line, nothing happens. It just returns instantly. I then switched to the filemanger and tried to run it by double clicking. The first time I double click it, I get a nice wx window and a dos box. I close this, then click on a.exe again. A dos box flashes and goes away instantly. No window. I double click it again, I get the wx window and a dos box. This repeats for as long as I've tried it.

I'm guessing this is some bug with how PAR is extracting the files it contains, but I have no clue what to do about it. Anyone ever heard of anything like this?

I've had something like this in that the dos box prints and finishes to quickly to see. Try putting a break at the end, `sleep 5 or print "hit any key\n"; chomp($dummy=<STDIN>);` might work. Just a thought. "Pain is weakness leaving the body, I find myself in pain everyday" -me	[reply] [d/l]

Well, I tried adding a "<>;" at the end of the script (after the mainloop function is called), and now I can't run it from the file manager but running it from the command line gives me the same first it works, then it doesn't as before.	[reply]
