The problem resurfaced again on my servers running 1.7.4 today. These are=20
IIS 7.5 servers and the file in question was an aspx file.
Navigating to the the directory in powershell I see the file has the=20
correct time stamp. Opening the file in notepad I see the old file.
Performing fs flushv on the directory allows me to open the correct file=20
in notepad but IIS continues to serve the old file as if it hasn't=20
received notification of the file change.

Did upgrading to 1.7.4 fix this issue?
I have had reports on similar issues on our Windows 7 lab computers (with=20
1.7.1 and maybe 1.7.2). After upgrading to 1.7.3 I have not heard of this=20
but that might not mean that the issue is gone. I have never been able to=20
replicate it myself though. This and the next week we will upgrade to=20
1.7.4 and hope that it will perform even better.
