Try clicking on a monster

Kinda random what I just said, but I'd be curious to hear if anybody has had any close calls with what I described in my first paragraph

I was in Slime Tree on my magician and I was low in health. I forgot to put my HP pots on a hotkey (long story >_<), so I went to double click one to use it and accidentally clicked a slime and opened the monster book. I lagged and died. Only level 15ish so it didn't matter much, but still... Yes, I have a laptop.
