This is happening occasionally and I can't nail the source. What happens is that sometimes after my Mac wakes up from a sleep, I can not launch any apps using Launchpad. I can click the launchpad icon, and I can see the launchpad, but whatever app I click there – it won't run. Only after few minutes all the apps that I've clicked start all at once and then launchpad starts to work fine.
During this stall I can run apps that are in my dock without a problem – they start immediately. I can use terminal and work normally within open apps. The only problem is that for few minutes I can't launch new apps from launchpad.
What's interesting, during this stall, when I click on app icons in the launchpad, the launchpad does not close. I can see it all the time. I need to click on a blank space around icons to close the launchpad.
Any tips on this? I tried looking at the syslog, but frankly, I have no idea what to look for. system.log is a bit littered with stuff that I'm not familiar with. I don't even know what to look for.
[Update]
It happened again today. I wanted to launch Notes app and the launchpad stalled again. I've tried searching logs and this is what I've found:
This entry is really annoying – it is littering the whole log, so I've removed it from results:
sharingd[322]: Stopping Handoff advertising
This is the log from the moment I noticed that launchpad is stalled. You can see that I've immediately launched console to tail the system.log. I can't tell the exact time. Everything lasted for 2-3 minutes:

[Update 2]
Happened again today. I've looked at logs again and it looks like it's caused by Finder which tries to connect to some remote machine that is no longer available.

I'm not sure if that's coincidence, but after last message all the apps that I've clicked in the launchpad have started immediately. Any ideas why this is happening?
Best Answer
I suggest you reset launchpad as this appears to be a bug/glitch of some sort.
Go to the Finder. Hold down the Option key and click on the the Go menu. Select Library. Look for the Application Support folder. Open it. Look for the Dock folder. Open it. Locate files ending in ".db". Drag them into the Trash. Go to the menu and select Restart... Click on the Restart button. (Alternately, you can simply log out and log back in, if you prefer.)
