On May 29 2003 I found a bug in OpenOffice, and submitted it in proper form: if you are moving through text by sentences — and the ability to do this was the first thing I liked about the program — the cursor won’t stop after a sentence where the last word is capitalised.
It is small, irritating, and not very complicated.
By June 12 2003 it had been identified by a responsible developer. By June 29 2003 there was an internal fix. This actually appeared in an alpha version nine months later on April 24th 2004. It has, however, been replaced in these alpha versions by a new bug which means that moving backwards by sentence is completely broke, and now moves (or deletes) by paragraph, or sometimes two sentences, instead. So I am still skipping sentences that end with a capital letter.
