Thanks for the report. I just committed your fix to the 0.2 branch. Please svn check out https://udeproject.svn.sourceforge.net/svnroot/udeproject/uwm/branches/BRANCH-0.2 (revision 242 or later) and tell me if the issue persists. There seem to be some other issues with 64 bit systems in 0.2.9b which should be fixed in that branch. It will be released as 0.2.10 if no further issues are reported...
