What actually happens when you specify a pre or a post command. My pre command successfully executes the .bat file to which it points. But I also have a post command which I want to evoke the file Run ProBak.rrr Run ProBak.rrr is a run document for another backup product. Doubleclicking on Run ProBak.rrr launches the operation successfully. The operation also "tests" successfully from Acronis. However, when I point to that file named Run ProBak.rrr from the Acronis post command feature and let Acronis evoke it.. all that happens is that the other program's flash screen starts, then ends, then Acronis shutsdown. Should I be including Run ProBak.rrr in a .bat file, or something else to get it to execute by Acronis??
