Taking a guess, it is looking for some resource (debugging files, for example) on your network. Check Tools, Options, Projects, VC++ directories. In the right hand pane, check the settings for each set of directories. Another thing to check is your PATH environment variable. If you've got a network share in any of those places, it could be the IDE is searching for a file and waiting for the network to time out. Software Zen: delete this;

Same thing started happening to my installation. I finally had to just reinstall everything to fix it. Not the answer you're looking for, but that's one man's experience.

Thanks, but as you know that gives me the result, not the cause of the emitted code. I figured out I can use the GNU cpp.exe to get most of the info I want. Just need to get at all the built-in MSC defines. There is a list of them in the compiler docs, but it seems to be a small number of them... Thanks again. Chas L
