Vista - Vista Search Kills Windows Explorer

Hi All,

I'd appreciate any help with the following problem. When I use the search
bar in Windows Explorer it kills the application ("Windows Explorer Has
Stopped Working") after about the second keystroke. Sometimes it makes it to
the third. If I cut and paste the whole search term from another application
- it seems to do OK with only the odd hissy-fit!

The cut & paste option is really painful so it's not an option to carry on
like this - nor is it an option to ditch Vista (Home Premium Ed) - give me
strength!

If no-one's got any ideas how do I get in touch with those *wonderful*
people at Microsoft - or should I assume that they're attentively following
every thread on this forum ;o)

Cheers ......
