Are you sure your package specification is alright and WPKG-GP doesn't do any 
fancy thing to the Wpkg-GP.ini file while running? Perhaps this is a glitch of 
Windows when reading modification dates of files which are currently locked for 
read/write as I assume WPKG-GP will be running while WPKG is running. Solution 
might be that WPKG-GP should read the INI file and close it before invoking 
WPKG. Or open it in read-only mode. However these are just wild-guesses.

As you say it works fine with Thunderbird and Firefox I don't expect this to be 
WPKG code issue. Moreover I have just done some fixes in WPKG 1.3.1 and released 
it as WPKG 1.3.2-RC1. I also did some reference-date comparison tests and all of 
them worked fine for me.
