problem with yahoo briefcase

it happens every time i try to upload a file to my folder. in fact i am unable to do anything after clicking 'add files' cos the page im directed to....

http://f1.up.briefcase.yahoo.com/edi...bub_action....

automatically refreshes itself and turns white (nothing on the page just a white screen).

no error messages just the words 'script error' on the status bar of my browser. (sometimes it just says 'done').

there isnt any problem anywhere else on the site just with the briefcase.

1. log in to yahoo email

2. go to yahoo main page

3. click 'briefcase' at the bottom of page under 'more yahoo services'

4. click 'add files'

5. select folder 'my downloads'

6. im directed to this url: http://f1.up.briefcase.yahoo.com/edi..._do_bub_action

7. the page refreshes by itself and goes to a blank page.

im very sure its not a virus or spyware (there wasnt any to get rid of) cos it just happens with this site . i cleaned out my temp files and history but nothing works.

does anyone else experience this problem? what do i do to now? :(
