Vulnerability Development: Strange behaviour in Win2k

["npcompleter" <npcompleter () hotmail com>]

Hi all,
When I was viewing emails using Outlook 2002 (aka Outlook XP) on a Win2k
pro SP2 box (Version 5.00.2195), I noticed something strange.

A message mentioned a URL. I selected the URL and copied it to clipboard
using Ctrl+C keyboard shortcut (and later, using Copy command in the
context menu,) that's when something happened.

I tried to move the cursor to the system tray, but the cursor refused to
move a millimeter below the status bar, or it moves for 1/10 second and
it gets back above the status bar as if it was locked there. When I
waited for a few seconds, everything went back normal. I copied
different text to the clipboard, the cursor moved normally. I copied the
http://xx.xx.xx.xx/ part only (without filename), the cursor refused
once again. I tried different text containing "http://"; and got the same
result, even with a few leading and trailing spaces. I tried to copy the
text and waited for about 7 seconds (On PIII 450 MHz with 256 MB RAM),
everything went normal. The same behaviour happened whenever I copy the
"http://"; part from anywhere (browser, text editor,...etc).

Could anyone replicate this?
Does anyone think this might have any (possibly security) significance?

P.S. This happened more that once, but sometimes I restart my Outlook
and it doesn't happen!

Cheers
