<isindex /> appears unbidden

I had a file on the order of 300KB in size whose
contents (below) Amaya somehow (?) decided to replace
with an <isindex /> tag.  My last action before this
spontaneous self-destruct was entry of carriage
returns above a series of paragraphs that were each
prefixed by the square root symbol (as it also looks
something like a check mark). 

platform: Windows XP Pro, Amaya 8.5

fyi,
george
