Subject gsec and stdout on Windows 7

I have a problem with gsec's stdout under Windows 7 64 bit. When I say
gsec -z >out.txt
nothing is shown on the console and I find version information in file out.txt. So far so good. But when I say
gsec -display -user...and so on >out.txt
again nothing is shown on the console but the file out.txt is empty although it gets created. When I omit >out.txt I get the desired information on the console so the parameters are okay. This happens independent from the directory in which out.txt shall be created.

Any idea what might be the cause of this problem?
