Hi all,<BR><BR>This is the problem. I have a page that I can upload a word document using aspSmartUpload. It&#039;s works fine. Then I use javascript to popup a window to view the document (ie. window.open("filename.doc")). After viewing it, I close the view window, then I go back to the upload page to upload another file to overwrite the one that I just viewed. But aspSmartUpload is unable to upload the new file. And, I find that if I wait for a while, and try again, it is able to upload. I suspect that there may be a share violation problem in that somehow IIS is not releasing the doc when the view window closed.... ? Can anyone help?<BR><BR>aifong<BR>
