I\'ve built a GUI using Swing and the MigLayout.
I am using Eclipse 4.2.2 (64-bit) on Windows 7 Ultimate. Every time I click back into the window to edit my code, a
"unhandled event loop exception .. no more handles" error (in my case) was caused by the driver of my mouse ! closing my mouse driver solved the problem. It has nothing to do with Eclipse versions, I tried almost all versions after Helios(in both 64bit/32bit) and all of them have the same problem, I also tried to add Eclipse/JRE variable path within advanced windows settings "environment variables". To help you to resolve this error try to close up unused applications and drivers.
