"Application" global variable not recognized

I work on a large project in Delphi 5. Today, after merging two branches of the app together, one of the hundreds of units, UnitMain (the main form's unit, would you guess) stopped recognizing the Application global.

This is a rather bizarre problem - I could get the program to compile by defining Application: TApplication in UnitMain, and setting that to the Application from our .dpr project file, but that leads to an access violation, which isn't much of a surprise with Application being the special thing it is.

I'm hoping someone has faced the same problem before, or knows enough of Delphi VCL's inner workings to help me out here.

unit UnitMain;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  Menus, ComCtrls, StdCtrls, cxButtons, ExtCtrls, IniFiles, ShellAPI,
  LMDControl, LMDBaseControl, LMDBaseGraphicControl, LMDGraphicControl,
  LMDScrollText, cxControls, cxContainer, cxListBox, Psock, NMFtp, db, DBTables,
  FileCtrl, Configs, cxHint, DSetFunc, OleCtrls, DsInformation,
  InterAppComm, ActnList, ADODB, OleServer, CRAXDRT_TLB;

The exact error is that the compiler does not recognize Application in this unit. For example, for a Application.ProcessMessages; call, the error is "Object or class type required". None of the other units has this problem.

I think it is most likely that you have two symbols called "Application" in scope, and the one from the Forms unit isn't the active one. Make sure the Forms unit in the uses list comes after any prior unit that contains a symbol called Application.

But, you need to provide more information. The exact error messages, etc.

我很高兴看到所有的东西都能正常工作，但我会补充说明解决这些问题的另一种方法，特别是如果你不想重新安排你的使用条款，就是将单位名称作为你想使用的任何名称的前缀，例如。

Forms.Application.ProcessMessages;

What units are in the uses clause at the top of the file? Application comes from the "Forms" unit.

eg.

unit MyUnit;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms;
