Lately, I have been having a problem with my zip uploads being corrupted as reported by my product tester. I find this odd as they work fine on my machine and none of my beta testers have reported this error. In order to properly discern why this is happening, I needed to know if there was an inordinately high volume of corrupted zip files. The other problem could be winzip version numbers. I use the latest version of Winzip and I have read on some websites that this might be a backwards compatability issue. Terri
