The behaviour in 1.056 is the same as in 1.054. In 1.055, it didn't generate any error messages, but that was because the compiler was crashing! Interestingly the code works on 2.043 and later. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
