Can't find temporary directory on Windows

[John Doe]

I just installed SLIME on my Windows 7 system, and when I run 'M-x slime' I get a warning during startup:
    *** - OPEN: Directory #P"C:\\Users\\MYNAME~1\\AppData\\Local\\Temp\\" does not exist
Thereafter, I get a continuous message in the emacs minibuffer:
    Polling "c:/users/MYNAME~1/AppData/Local/Temp/slime.10396".. (Abort with `M-x slime-abort-connection.)"
The directory it's checking is coming from my %TEMP% environment variable, and it definitely exists. The slime.10396 file it's polling does not exist, so I guess it failed to create it.

If I modify my %TEMP% variable to point to "C:\temp" instead, both the startup warning and the minibuffer message disappear. So, it seems like SLIME is having a problem with the default definition of %TEMP%, which is defined in the registry as "%USERPROFILE%\AppData\Local\Temp".

I didn't try to modify %TEMP%.But it work good on another PC with same OS windowsXP SP3,and %TEMP% is default.
