lately my KPA has become rather sluggish on startup, and it goes to a generic screen for awhile before it's finished starting.
Yes, same here... I'm running about 900 rigs. I need like 2 weeks time (which I don't have right now) to clean out everything and sort the good from the bad (so to speak).
I'm just wanting to make sure there's nothing wrong with my KPA... Has anyone else experienced these symptoms?
Yes, I can confirm this (see above). It's normal - nothing wrong with your KPA. Time to clean the KPA and get rid of the stuff you don't need/play.
