How to unpack dos lzexe packed exe?

[jonwil]

I have an exe file (16 bit dos) that seems to be packed with lzexe.
When I run unlzexe on it I get this:

UNLZEXE Ver. 0.81
Detected size of File is 27837 bytes
file 'mbucks2.exe' is compressed by LZEXE Ver. 0.90

but all I get as output is a zero byte file named the same as my exe but called .exeNEW instead of .exe

How can I unpack this exe (which btw does work just fine in DosBOXs)? (I want to throw it into IDA to reverse engineer some things)
