Stuart,
Do you mean that the VFP8 crashes whenever you other app with this bad project is open?
If so it sounds like you've got some really odd pjx corruption. Just delete TheBadProject.pjx/pjt files and start a new one. Just add the main prg and do a build project on it.
>I have one project in vfp8 that if I start VFP8 up then click on outlook express vfp8 crashes. I have tried recompiling, and deleting the resouces files. I have other projects and this does not happen any ideas ?
