Redirect stdout of a Windows command line program under wine

I run a Windows command line program (that I can not make accessible) with wine. It apparently writes something to stdout and I'm trying to capture that output, but I can't redirect it. No matter if I redirect stdout or stderr to a file, the program output is still printed on the console and is not written to the file. When I redirect stderr, the wine output goes away, but the program's output is stilled printed on screen. wine program.exe > out # File is empty, program output printed on screen wine program.exe 2> out # Wine output gets redirected to file, program output still printed on screen If I redirect both, the output is neither printed on screen nor written to the file. **Edit:** On Windows, behavior is similar, but when redirecting both, everything is still printed on screen. Here are some examples with the complete output. $ wine program.exe fixme:winediag:start_process Wine Staging 1.9.23 is a testing version containing experimental patches. fixme:winediag:start_process Please mention your exact version when filing bug reports on winehq.org. output by program.exe fixme:msvcrt:__clean_type_info_names_internal (0x100aaa54) stub When I try to redirect the output, this happens: $ wine program.exe > out 2>&1 $ cat out fixme:winediag:start_process Wine Staging 1.9.23 is a testing version containing experimental patches. fixme:winediag:start_process Please mention your exact version when filing bug reports on winehq.org. fixme:msvcrt:__clean_type_info_names_internal (0x100aaa54) stub I.e., the program's console output is completely missing. The program still works fine and writes some files it's supposed to write. As a check, I did the same with pngcrush, and I get what I'd expect.
