>Maybe I'm missing something but error message "Compile error in file d:\vfpclien\www\universa.app" says that there's problem/error compiling universa.app. It isn't COM object.

If it would be an error from the project at compile time, that would mean the compilation would work. In my case, it isn't. There is also no error in the project. Basically, it's quite simple, when it does that, I just restart my application and click again on compile and it works. So, no change in the code, not even one task manager flip to the development environment. This is intact. I just restart my application (the console monitoring for compiling and uploading to server), retry and it works.

As I said, this is a problem with how Visual FoxPro handles its memory management. I really don't understand that but something got stuck in memory sometimes and this is why I only face this situation occasionnaly.
