The following script works fine if loaded into the IDE, and
run without any breakpoints:

use strict;
use Switch;
use Text::Wrap;
while (<>)
{
print "$_";
}

I provide a text file as a single start parameter. This
just basically prints it out. I wrote this to debug
another (much longer) script that was hanging in the
debugger. Obviously I am not using Switch or
Text::Wrap here, but I am in the other script. The
other script also runs fine if run without any breakpoints.

If a breakpoint is added, the following is written to the
console:
Entering open perl debugger, connecting to port
2084...connected.

Then it hangs and never steps into the code. Very
rapidly this ends up consuming the available memory! I
have to force a script termination.

If you comment out the 'use Switch' line above, it runs
fine in the debugger.

Some hopefully pertinent details:
OS - Win2K Pro, SP3
Perl version - 5.8.1.807 (from ActiveState)
OpenPerlIDE version - 1.0 (I got the latest
dbTemplate.txt)

my email is doug.mcelroy[at]harlandfs.com (replace [at]
with @).

Thanks,
