Noël said that the browser search is now recursive but m not sur elf the significance of it. I d know that it can now be pointed to anywhere on you computer or network.

For a two to thirteen second delay or difference in loading, "optimization" in Sonar would be appropriate and welcome, especially when it is coupled with common workflow ops like changing screen set. But I believe "several minutes" as reported here by mrs3 shows something terribly wrong (with something we haven't guessed yet), not just an optimization issue as others are experiencing.
 
Since the browser's file explorer seems to remember per project where it last explored, I wonder if there is much difference in delay based on that.

Double checked, removed some plugins I dont use, no changes to the delay I get while loading projects or switching screensets where browser is open.
I also removed, tested and reinstalled dropbox.
 
The delay seems to vary for some strange reason. But its always in the range of a few to serveral minutes.
 
Does anyone have a Y510p running Sonar? Latest BIOS (maybe the trouble started after a BIOS update, not sure)
