Sergey - again thanks as I think you are onto the right track. But not sure how it became encrypted. More important, when I de-select encrytption - it keeps re-selecting that option. Any idea why that should be? Denis


>I have never had any trouble compressing my application using my zipping prg (PowerDesk). However, for some reason, the main .exe file (c. 4 mbytes) refuses to compress. I have rebuild the project etc. but it still compress 0%. Any clues! Thanks Denis

Maybe your project is encrypted?
