Ok. I have to admit I run my compiler from a short cut to a bat file which sets up the environment for 64 bit building and I have another to run up the x86 compiler. So I run with separate environments. Well, if its something you want to chat about in PM or on the user convo or something then let me know and ill go through what I have or do if it would help out get it sorted. Oh I should say also that I dont use the VS projects as I run out of makefiles so maybe I bypass those kinds of project and settings issues as well. I just use the VS IDE to kick off the make and use its editor which I still think is the best out there. But I always think that the VS project format really sucks. It seems to need updating all the time and you cant go back to an earlier format without pulling it out of some code repository or something. I like to see all the settings I am using instead of the dialog panels with them all on.
