On my work machine, I don't have DF start automatically, so it's seems kind of strange that it takes so long to load when you start it. I believe this is to address some people's problem with it starting up too fast (for them) on boot, but when you start it manually, you think something's gone wrong (because it seems to not be starting) and you're apt to keep clicking the icon to get it going... (just an observation)

Sorry for the delay. I set it to start with the task bar, so it takes a long time before I see the DF task bar show. Long enough that I frequently hit the icon again because I didn't thing it started..

I usually have it set to start on boot, so it's not noticeable, but on my work machine I start it manually. No biggie.

In retrospect, I think you've done a good thing here. A lot of systems have so much loading at once, it nearly hangs the system. Having DF delay a bit makes a lot of sense.
