Hack - Win32 Hex editor (REXX enabled)

I found that, if you try to run the program from e.g.
with a file association and send it a path enclosed in
quotes, it tends to crash.

The command I used to execute it (which caused it to
crash) is

(Drive & Path to program's folder)\Hack.exe "%1"

However, this works properly:

(drive & path to program's folder)\Hack.exe %1


Using v0.4 on a system running Windows XP Home SP2.
