url msg problem

[aviovda]

dear friends

as i post a page with the url
http://10.10.10.2/scripts/cgiip.exe/WService=prod86e/mrpframes.html?part_id=CSA-0100KM15

i get this msg

WebSpeed error from messenger process (6019)Messenger: URL contains invalid syntax. (6369)

if i add blank to the url ends, or simply cut and past the url again there is no problem

any ideas

thank you very much.
