Hi Larry,

Foxtools doen't really come into play to create a single instance app. There are a couple of ways to do this. Vlad Tatavu has a file here that will allow you to do it via DDE. My Is_Run32 function could be used. Personally, I use (and prefer) the method I wrote about in the November (I think) 1998 issue of FoxPro Advisor. The article is on-line at the Advisor site, and it includes complete code.
