Strange issue with location list

Members from my forum did report that location info (from member profile page) is getting lost.
I can reproduce this problem in both my forum and here.

If i enter my profile page, i select my country and click update the info is here; location is displayed. But if i hit update profile again (without touching location list list) location is lost !!

I can't reproduce this with IE (only firefox)

NO problem, glad i can make this aplication even better.
Here is another google-bug. For unknown reason sometimes googlebot is requesting /default.asp?C=
Don't ask me where this empty C queryy string is from but is causing a server error.
I fixed this with

If IsNumeric(Request.QueryString("C")) Then
     intCatShow = CInt(Request.QueryString("C"))
Else

in the line 128 of the default.asp

Borg,

regarding the first issue with location list box i think i did find what was causing this.
Line 1651 in register.asp looks like

        <option value="<% = strLocation %>" disabled selected><% If strLocation = "" Or strLocation = null Then Response.Write "-- " & strTxtSelectCountry & " --" Else Response.Write strLocation %></option>

I have deleted "disabled" statement and now the line is

        <option value="<% = strLocation %>" selected><% If strLocation = "" Or strLocation = null Then Response.Write "-- " & strTxtSelectCountry & " --" Else Response.Write strLocation %></option>

This seems to work in both IE and firefox, but i still need my users to test it properly :)
