sticky insert key? Can you repeat the condition?
Could be... and on that subject, sometimes, the short cut keys can be a bit of a "bind."
I keep promising myself to unbind all of my keyboard short cuts one day and only re-assign the ones that I use. I have found myself getting in a right pickle at times when something happens on screen and I don't have the slightest idea why. More often than not it is a random key hit from my big fat fingers.
