The PowerBrowser is a public domain addin. At the time when I write this, it is only available for Visual FoxPro 5.0, but I plan to update it for Visual FoxPro 6.0 in the near future, so by the time you read this, you should be able to download a new version from my web site (www.eps-software.com).
I have yet to see this tool on your web site. I am curious if you still plan to release it?
