Dupe of something involving NewFile.fillSubMenu I think. Also apisupport is scanning for modules in the background. Probably WONTFIX but needs to be classified.
Comment 3 Michel Graciano 2010-11-05 20:04:59 UTC 
In my case, I think the problem was hg process looking for changes, running a hg status command. This generates a lot of IO activity which probably reflects at IDE performance.

About Report #155410, Id #517018. I commonly get 10's of seconds hang after clicking on something in favorites folder so I can open it as a project. I wonder if its looking at too many things in Favorites rather than just what I clicked on.

I would think all that's needed is to look for nbproject under the one subfolder I click on.

I have a link in Favorites to the root of main-silver source, very painful.

Observations:
1) start IDE, wait for "opening projects" to finish, things are idle.
2) select favories tab, wait for mercurial action to finish
3) open folder-link to main-silver, get very large number of subfolders
4) scroll favorites up/down seeing all the modules, NB gets very busy for
   a minute after stop scrolling.
   NOTE: there is no status bar indication of scanning or other activity.

Waiting for everything to finish and there is no hang when clicking on a folder.

It doesn't always hang if you click while it is busy. Clicking for the context menu immediately after expanding the root folder is pretty reproducible for getting the long hang.
