This unusual activity did not occur on previous versions of Peachtree we have used. It occurred when we took SR2, so we unistalled that and the problem went away. We recently had to take SR4 (2-3 included) because of the credit card processing feature change and this problem came right back. When it happened before I contacted tech support and basically they thought I was crazy and had no resolution except to uninstall it.
Our current is: Release: Peachtree Complete® Accounting 2006 (SR-4) Build: 13.0.04.105
