I have a Dell computer with Home Vista and IE7 that came with the system when I purchased it about a year ago.

I have no problems accessing any Air Canada or Aeroplan web pages except when I go to the "manage my bookings" page:

http://www.aircanada.com/en/travelin...ing/index.html

To view an itinerary using my booking reference number I get an error page with a whole bunch of error messages like this:

java.lang.IllegalArgumentException: Empty country component in 'value' attribute in <setLocale>message:Empty country component in 'value' attribute in <setLocale>stacktrace:

The same error occurs using the Firefox browser making me think it could be a "Vista" problem rather than a browser problem.

This has recently started - until a month or so ago I was always able to look up my itinerary using the booking reference number on this computer. I have three booking references for three different trips and none work.

When I try the booking reference numbers on my wife's computer running XP I have no trouble accessing any of these itineraries.

I have no problems accessing any other WWW sites.

Anyone else having this problem?
