Has anyone run into strange programming errors by the Windows file blocking mechanism? I believe it was something introduced into SP3 so when you download an executable from the internet it blocks the file. You have to right click on the file and click "Unblock File" from the general tab.
The first time I ran into it was when I was attempting to help a friend through copilot.com. The program wouldn't run but also didn't spit out any errors. Just recently, I wrote a C# service to download files that encountered odd behavior until I unblocked the file. I didn't record the error stack, but it certainly wasn't helpful in determining the cause.
As a test I downloaded PuTTY and a warning/continue prompt is raised when trying to run if the file is blocked. Yet when I downloaded psftp.exe, a command line app, it was able to run without error.
Anyone have experience with this or know what kind of behaviors it prevents? Also, is there a way to detect when a program is affected by this?
Thanks, Daniel
