I am using the latest update with Fire fox and have Vista home premium 64 bit.

When I composing a email in Hotmail, the auto spell check will indicate an error in part of the words that are not misspelled with the red wiggle underline.
As an example,  Typing the word "those" it will underline the "ose" of that word those. If you right click the error, it give suggestions for the part it underlines ("ose") , which is unusable. If you use "those" again in your same composition, the error does not come up again.

This happens mainly with simple words and usually errors the end of the correctly spelled word. As far as can tell it is only on my computer.

Thank you
