           Summary: SetWindowHookEx fails to inject DLL conatining the
                    HookProc if...
           Product: Wine
           Version: 1.1.2
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: user32

SetWindowHookEx fails to inject DLL conatining the HookProc into another
process if the DLL is linked with another DLL in the same directory which is
not on PATH.

Suppose DLLA_GetMsgProcis is in A.DLL, and A.dll is linked to B.dll, with those
code:

hwnd = FindWindow("Notepad",NULL);
idThread = GetWindowThreadProcessId(hwnd, NULL);
SetWindowsHookEx(WH_GETMESSAGE, DLLA_GetMsgProc, hinst, idThread );

SetWindowsHookEx will fail because it can not load B.dll which is imported by
A.dll.

If hwnd is created by current process, there is no problem. But in above code,
Notepad is not the current process.

I have created a simplest test application (attached) with source and compiled
exe/dll to show the above bug on wine.
