I am getting this rather confusing compiler warning:

[DCC Warning] W1056 Warning: Duplicate resource: Type 14 (ICON
GROUP), ID MAINICON;
File C:\dev\dispense\trunk\dev\source\mountaintop\dispense\MtnDispense.res
resource kept; file
C:\dev\dispense\trunk\dev\source\mountaintop\dispense\MtnDispense.res
resource discarded.

In case the formatting isn’t clear; the two paths it mentions are identical.

The application doesn’t have any entries under Project->Resources

The application has a custom icon, defined under Project->Options->Application->Icon.

Does this warning mean anything? And how can I remove it?

    It means the resource file is being imported more than once. You should only have one

    {$R *.res}

    in your dpr file. To fix the error, remove the extra ones.
