Outlook 2000 SR1 Hangs while trying to add an attachment

While using MS Outlook 2000 SR1 with Windows 2000 SP4, I open a new mail, then I click the "clip" icon to insert an attachment. Nothing happens, it just sits there moving the hourglass.
It looks like it freezes doing something. So I would like to remove/reset Outlook settings. I have already deleted the OUTCMD.DAT file and it didn't help.

I think the Outlook is trying to open the last location used to insert an attachment, such as a network drive or cd rom.
If this is the case where in the registry can i find and delete such entry? Or maybe totally reset outlook?

I already unistalled the office 2k suite, rebooted and reinstalled office 2k and i have the same behavior.

It was not behaving like that a few days ago, but as usual, the end user does not know what she did and according to her, she did nothing.

Thanks for your help.

1. A new update may have changed how Outlook handles attachment. Outlook 2000 should have SP3. Go to Office Update site and click on "Check for Updates" in the left menu.

2. Outlook blocks certain updates. So you need a registry edit to allow certain attachment extensions.  Add the attachment extension to Level1Remove registry key

Best wishes!

The hard disk crashed and it seems that outlook was only complaining of an upcoming disaster: failure to read hdd.

So i will close this and award you the points because there is no need to continue to troubleshoot this one.
