printf not working in Vista?

Hello,

I use printf("some message") many times in my game to troubleshoot. I use that on two XP boxes no problem but I don't see these messages when I run my game on a Vista box

Any ideas?

Thanks
Gerrit

i see them perfectly clear, using vista

Strange Croman. I only have one Vista box so I can only verify on one box.

Did anyone else see that problem?

Tried with "error("something");" instead of "printf("something");" ??

Yes error does work thank you very much for the suggestion
