BUG# odbcdbase: 2126 (1.01.1928)

SYMPTOMS
========

When an ODBC application, using any of the desktop drivers (dBASE, FoxPro,
Paradox, BTRIEVE, Access, Excel, and Text), executes a USE statement, a memory
loss of 2048 bytes occurs. For example, the following sequence of calls exhibit
the behavior:

     SQLAllocEnv(&henv);
     SQLAllocConnect (henv, &hdbc);
     SQLDriverConnect (hdbc, hwnd, "", 0, szConnStrOut, cbConnStrOutMax,
                       &cbConnStrOut, SQL_DRIVER_PROMPT);
     SQLAllocStmt(hdbc, &hstmt);
     SQLExecDirect(hstmt,"use c:\\",SQL_NTS);
     SQLFreeStmt (hstmt, SQL_DROP);
     SQLDisconnect(hdbc);
     SQLFreeConnect(hdbc);
     SQLFreeEnv(henv);

STATUS
======

Microsoft has confirmed this to be a problem in ODBC Desktop Drivers version
1.01.1928. We are researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.
