exec("cmd.exe /c dir",$result,$status)
gives good output to result array.


exec("cmd.exe /c dir>c:\TEMP\test.txt",$result,$status)

fails with access error.

User running website has full access to C:\temp.
----------"------------- read access to cmd.exe.

Loggin on to machine with same user account and opening an cmd windows & running the full cmd.exe /c etc.etc. works...

It looks like an bug, but I might be very wrong. If so, please to hesitate to tell me that... :)
