It seems that there is a pretty significant bug in Pocket Word. According to a post in
PPC Magazine's blog, in some cases if you enter "->", which is not uncommon in documents, you will crash Word and lose all your work. This apparently applies to both WM2003 and WM2003SE. The additional resources listed below may have information about whether or not it applies to WM2005.
