BSP page only works for me

Question

Hi,
I have a very weird problem with a BSP-page I created.
The situation is the following:
- I can run my BSP page the way it should (it uploads a file of name e.g. TEST.CSV to the application server, and first checks if the files selected is really TEST.CSV.
1 - When somebody else tries to acces my bsp page, and logs in with their own SAP login, they get the error, saying that the filename is not TEST.CSV
2 - When I login with my SAP login (working in situation 1) on their PC, it gives the same error, saying that the filename is not TEST.CSV
3 - When somebody uses my PC (from working situation 1) and logs in with their own SAP login, it still gives the same error
so: only when I login with my own SAP login on my own PC, the PC does what it should do.
What can be the problem?
the other users should normally have more authorizations than I have, so I guess that's not the problem...
ANY! ideas are welcome!
thanks a lot, points will be awarded of course!

Ok guys, I have found what is the problem: Internet Explorer.
Everything works perfect on Firefox, but in Internet Explorer, it always goes to the "wrong_file.htm" page like you can see in the code below. Some of the elements used must me firefox-only, although this really surprises me.
Any user can run the BSP perfectly on any pc, using firefox. Using IE, it doesn't work.

  find multipart containing file
clear error.
    num_multiparts = request->num_multiparts( ).
    while i <= num_multiparts.
      entity = request->get_multipart( i ).
      value = entity->get_header_field( '~content_filename' ).
      filenamecheck = entity->get_header_field( '~content_filename' ).
      if not value is initial.
      found a file!
        navigation->set_parameter( name  = 'content_filename'

        TRANSLATE filenamecheck TO UPPER CASE.

data: data_TAB type table of string, LIN TYPE LINE,fname type string.
split file at CL_ABAP_CHAR_UTILITIES=>CR_LF into table data_TAB.

OPEN DATASET fname FOR OUTPUT in TEXT MODE encoding default.
if sy-subrc gt 0.
WRITE: / 'Error opening file'.
endif.
LOOP AT data_TAB INTO LIN.
TRANSFER LIN TO FNAME.
ENDLOOP.
CLOSE DATASET FNAME.
        exit.
    endif.
endif.
      i = i + 1.
    endwhile.
   if error eq 'X'.
navigation->goto_page( 'wrong_file.htm' ).
else.
navigation->goto_page( 'end_upload.htm' ).
endif.
