Typing too fast

I am not sure if it is a problem with my computer or connection, or it is a problem with this forum. I think it has something to due with this forum though, since I don't notice it when typing elsewhere. Sometimes when I post a reply and I type faster than the computer can depict, it will start messing up all the spacing. I have no idea why it screws up the spacing, and I know for a fact that it is not human error since it sometimes throws all the spaces together like 4 in a row. I think this happens more with responses than it does when creating a thread since it hasn't happened while typing this one up. Has anyone else had this problem?
