>I've noticed, that sometimes when I editing a thread title (say, if I see a typo) my keyboard doesn't function, e.g. I try to type a letter or a space, but nothing happens. I've realized today that it could be related with the fact, that the max length of the title is reached. Still, I'm curious, how do you handle this and is it possible to come up with a better solution?

To see if the max length has been reached, simply remove the last character and see if you could add one more.
