Resource Compiler changing the RC file

[JohnF]

I am careful not to let the IDE compile my RC file when altering say a dialog box because it will invariably change things.

1. Various identifiers will be inserted where there are not meant to be.

2. There are many #ifdef directives that when tampered with are gone.

Is it a bug or meant to be that way?

When just building the project there's no problem.
