logfile expected in wrong directory Y: instead of C:

[AndreasK]

when starting start.bat (after setup) I get the error message below. Installation directory is c:\OpenEMM on Windows XP. Y: is the home drive (company network). The problem stays the same after deletion of openemm, disconnection of Y-drive and reinstallation of openemm. The folder C:\OpenEMM\var\lock exists.
What tells openEMM to look for files on Y-drive ?

C:\OpenEMM>start.bat
Starting up .. home is C:\OpenEMM .. found codebase .. found database.
