Log Files missing on Metatrader4 installed on Windows Vista

 
I am looking for log files that usually reside (in Windows XP anyway) in the "c:\program files\metatrader 4\logs" directory on a computer running Windows Vista. In XP, I see a log file in this directory for each day that MT4 was opened, but in Vista I only see one old file from the initial installation, even though I can see account history reaching back weeks in the Teminal Window of MT4. Can anyone point me in the right direction?

Any help is greatly appreciated.

Thanks.
