I'm not sure what causes that to happen, but it happens to me quite often, especially since some of my posts can a little long winded. Never had that problem before on other boards. I suspect it has something to do with the v-bulletin software. On other boards running xmb for example, I have no issues. Pisses me off too. I learned the hard way. Now, if I even think I've been on a long time, I always copy my post first then try to post it. Stupid and unnecessary it might be, but it's the only thing keeping me from going postal.
