Thanks for the reply Frank,
There is extensive code in all of the files....None has changed and the
files open with out error on other computers. And the fact that there is no
option to debug is what confuses me, and that the error even shows up on
workbooks that have no code.

Hi
is there any code in these workbooks (e.g. workbook_open event code) and if
yes you may post this code

Hello group
I have a number of files (6) that usually open all at one time. Recently
when I open them all I get a Run Time Error 10004 "Application defined or
object defined error" The error seems to pop up on different files based on
the order I select when I open them. I can open less than 6 with random
selection and I still get the error. So I cannot tie it down to one
particular file. Also the RTE dialog does not give me a debug option. These
files are network files and the behavior does not exist on other machines on
the network, only mine.
Any ideas or suggestions?
Thanks!
