This usually happens when you are using a different eclipse installation to access your old eclipse workspace. Its something to do with the new installation not being able to access the secure storage created by your old installation. Here’s what I did to solve it:
Close eclipse completely. Now fire up terminal or command prompt or whatever and navigate to your home directory. In my case it is '/Users/manthan/' directory.
So I came across this recently and thought to share it with you guys.
First of all, exit steam completely. If you’ve closed it, check if it’s in the system tray and if it is, exit from there as well. Now, fire up Windows Explorer and go to where steam is installed on your computer. In my case, it was in the default installation directory (C:\Program Files (x86)\Steam).
So I had this problem the other day where I kept on getting pairing requests from my friend’s bluetooth keyboard. This was rather annoying as the pairing dialog kept on popping up every few minutes. So I googled around a bit and found the following solution which worked for me.
Turn your bluetooth off. This will disable your bluetooth mouse and keyboard and hence you will have to use the built-in ones.
The problem is that at some point the keyboard that is nagging you to connect would have connected to your laptop. Your laptop remembers this and hence accepts incoming pairing request prompting you to verify it.
