I haven't played too much with the Death Hover window...
I do seem to remember that it had two options, and selecting one of them may have given problems like you are referring to.
I also think that if the timer runs out, you will have that issue as well.
There had been issues in the past with the Hover window and seem to remember that it was recommended not to use it.
It won't be anytime soon, but I'll put it on my list if no one else gets to it first.
