Hi Jim,
Unfortunately, I can't help you, sorry.
But I would really appreciate if somebody could have a look at that issue. Still, I'm facing the behavior as well. The server tries to load the inactive version of everything. It doesn't figure out to use the active version of the unchanged files.
Sometimes I use the feature if I point the cookie path exactly to the location of the file I'm working on. This way, the server loads the active files except these on the path.
Best,
Mathias
