1 user getting inconsistent results from scripts

i am using fm8 on windows xp. i have a filemaker database running on a stand alone computer.
i have 4 users accessing the database through filemaker remote.
all 4 users have the same rights and priviledges.
3 of the users have no problems
1 user constantly gets inconsistent results from all my scripts.

the following is one of the scripts that prints a first page and then asks for a second page.
the 3 users always has the first page print then the prompt to turn the paper over and a back page print correctly
the 1 user sometimes prints correctly with no problem. other times it will print the first page and then 12 blank pages, or still other times it will print the 2nd page on the 1st page and then 12 blank pages.

any ideas as to what would cause this behaviour for just this 1 user.
