Try to add a -name option in your AddLabel.
In Win32::GUI 0.0.558 a name option is required for any windows.

From: "Becker, Joern {DR-N~Mannheim}"
I wrote a small Win32::GUI Testprogram, which works well with perl 5.6.0/NT.
Now i have changed to perl 5.8.0/NT and want to use this program, but now
when the program starts the first Window of Win32::GUI the following error
occurs:

Perl: perl.exe - Error in application
Instruction in "0x78...." points to mem "0x00000000". The command "read"
couldn't executed.
Click "OK" to close application.

The DOS-Terminal-Output is
...>perl win32tst.pl
Hello World!
CWD: I:\Proj\ApCv\PerlDos
MS-Domain: RBAMOUSER
GUI-Version: 0.0.558

...>

I think there is a real dump/trivial error, but can't imagine what will
produce this
"Null-Pointer assignment".
