You could use a semaphore. ie:

FUNCTION AppAlreadyRunning
LOCAL hsem, lpszSemName
#define ERROR_ALREADY_EXISTS 183
DECLARE integer GetLastError IN win32API
DECLARE integer CreateSemaphore IN WIN32API ;
  string @ lpSemaphoreAttributes, ;
  LONG lInitialCount, ;
  LONG lMaximumCount, ;
  string @ lpName
lpszSemName = "MyUniqueApplicationName" && Whatever you want per your app
hSem = CreateSemaphore(0,0,1,lpszSemName)
RETURN (hsem # 0 AND GetLastError() == ERROR_ALREADY_EXISTS)
