I haven't managed to get cp to do anything other that use the same mode as the source file for a copied file. What version of kdiff3 are you using? I ask because this fix looks like it may be relevant: http://kdiff3.svn.sourceforge.net/viewvc/kdiff3/trunk/kdiff3/src-QT4/fileaccess.cpp?r1=84&r2=96 The changelog for 0.9.95 includes this: - Fixed permissions when writing executable file.

(Un*x only) Hi Charles, I didn't thought of blaming kdiff3 which seems to be the real guilty for my problems. I'm using 0.9.94 version but I'm in the process of update. I'll try that version and report back if it fixes my problem. Thanks for your help! -- Best regards, Grzegorz Kossakowski ```
