>I just wasted about 30 minutes trying to get the class browser windows to copy a class from one library to another in VFP6. I followed the documentation which stated to open two instances of the class browser, open one class library in each window, then drag-and-drop the class between the two. However, I get nothing that way. I finally gave up and did it within project manager.

The trick is that you need to drag and drop the icon in the upper left-hand corner to the corresponding icon in the target object browser.

Of course, you could always you the command window:

add class myclass of myclasslibrary to mynewclasslibrary

HTH.
