Thanks for your help.

>>As far as my assumption is concerned if I place a wait window nowait after the Update it consistently works! Otherwise Word throws an exception "The instruction at 0x.... referenced memory at 0x... The memory could not be read". Now as this is not a Fox error I didn't think I could trap it - is that correct?
