3rd mouse button 15 sec delay in Explorer.exe

[bigHUN]

Third mouse button delays about 15 seconds in Explorer.exe or in MyComputer,
than the screen flicks and I have to 3rd mouse button again to get the menu
(copy, paste and so on).
The requested operation seem to me working correct, all the other programs
including Office 2007 seem to me working correct.
It is a fresh installation from hours ago, fully updated all the drivers and
software’s, taking as much as 15-20 hours effort, or maybe more.
This is what I could rewind: at the end of the renewal process I had 3-4
windows open and the next (last) installation started, so I want to stop the
Explorer.exe with the X button, didn’t react, hang and than others as well.
Instead of closing all the open windows I force the restart. Than I left to
sleep and the Norton 360 v3 was running a first scan all over night. Today
morning the issue with the 3rd mouse button menu was there.
Asus C90s notebook running XP-Pro SP3; Nvidia, IE7, Office 2007;
Some of the older (2003-5) forums mentioning some Eplrorer.exe corruption,
my guess the mouse driver and overall functions working well in rest of the
programs.
Can you help me please.

Searched thru some forums and gained some info:
- the Shell extensions for context menu got corrupted somehow.
- download the ShellExView, but don't know how to use it
- download the XP SP3 and re-run it but didn't fix the problem
- called Symantec and we had a live session, he recommends an expert to take
a closer look
- shall I replace using explorer.exe with something else even better aps or
I could expect difficulties with that as well?
- is there any easy workarround with this issu or I shall better sitt down
again to format?

well,
solved with ShellExView
I was hesitating using it because this aps is unknown to me, but no reply to
my question so gave it a try. My plan was to go step by step, turn off the
shell extensions in groups for the programs by company name starting from
latest installed and going backwards. And I got it in the first try, got back
my explorer click contest menu and working fine. Two thumbs up for
ShellExView for this.
What about the program? Is it working? or not? I don't know yet, tomorrow is
a good day to push that button...
