Not letting me type certain words?

[parayna]

Hello, for some reason whenever I am writing on a page if I type a certain word, it takes away a few letters or won't accept it or something..

They are just normal words as well. At first I thought that they were typos so I went to correct them and I thought it had let me, but then the page doesn't change! Most words are fine. I think it has something to do with a coding language... the words it doesn't like have the beginning or whole code tag or something in them. These are some words it doesn't like (I can't remember all, but I will update it until the solution is fixed whenever I find more):

Interning changes to inteing.
Return changes to retu. (This messed up a link to an image I had on photobucket called 'Return Arrow'. I had to reupload it with a new name..)


..and for the life of me I can't remember any more XD I know that I have had about 5 more though (at least), I have had to reword a few sentences.. the only thing I can think of that I did differently was I added that code to the template files that HoF posted up a year ago that stopped the weird A character from appearing when you type in the adminCP and then go and edit a page. Not sure if that would be the cause though... hmm :/
