I had this problem occuring in the past.
While using IntelliJ 10, I think I almost never had it.
But now, with IntelliJ 11.1.2, it's happening often again: slow response while typing.
When typing characters in java code, IntelliJ is responding really sluggish and slow.
It really seems slower than 10 to me.
How can I stop it again?
Why does it have to parse stuff while I type? Can't it give preference to what I'm doing? I can wait a few seconds for an autocompletion, but I cannot wait more than 50ms for a letter appearing on the screen after I typed it...
