About 3 days ago my mpb suddenly lost the ability to upload images/documents via googlemail, this forum, etc. When i click on send (with an attachment) there is a brief flash in the titlebar and then nothing. as soon as i remove the attachment, it sends fine. Attempts with attachments on this forum result in an error message: [Safari can't open the page"http//macrumors.co...do=manageattach&p=".the error was:"POSIX error: Invalid arguement" (NSPOSIXErrorDomain:22) Please choose Report Bugs to Apple from the Safari menu....] Which I have done. Also reported issue to google. Of course, no reponse. In the meantime i have run the gamut of troubleshooting steps: Disk Utilities (permissions always fine); removed files from ~/library/input managers and restart; fsk- fy: applejack; reinstalled safari w/updates; all have gone without a hitch , yet the problem persists.
This morning i created a new user and attachment went through, no problemo!
However i'm stuck with this in my other account and am more than a little curious as to what is going on. No issues with downloads, or anything else for that matter

Don't know where else to look. Any ideas???
(need a better smilie for consternation)
