Okay, it seems that if you save the .css file after making changes, then return to .html file, the changes will show up in the preview window, at least within a very brief delay, which is okay behavior.
If I change the extension from .html to .php (which is necessary as I use php include statements here) it seems to be working also. The difference here is that the preview window will not refresh automatically when I return to it.
This is not too bad, at least it is mostly working now. I am having much better luck with it today
Btw, one other thing I notice is that sometimes the cursor disappears in the editing window and I have to restart the program to get it back. Just wanted to let you know about this also.
Also, sometimes the preview window (at least with .php file) will see the actual code in place of preview, or in some cases the page but without markup.
If I upgrade (apparently at full purchase price?), what improvements if any may I see with respect to preview feature?
Thanks
