when I am setting any type of hooks within a DLL and I want to print any information in a file from that DLL (for example at what time a WM_xxx message was sent or things like that) my hook callback freezez it just doesn't respond. I am using fopen,fprintf,fclose functions. I know this is the problem because when I use a messagebox for example instead of writting in a file it works fine. Can someone tell what is the problem. This used to work :) Sorry for my english gabby
