BUG# 9000 (4.20.00)
SYMPTOMS
When you are using DB-Library (DB-Lib) cursors in debug Windows 3.1, the following error message is generated:
GlobalUnwire: Object usage count underflow 0000:00F3 FatalExit code = 0x02F0 Abort, Break, Exit or Ignore?
CAUSE
DB-Library incorrectly calls GlobalUnwire under certain circumstances when using cursor functions such as dbcursoropen and dbcursorclose.
WORKAROUND
Start the DBWIN application that comes with debug Windows 3.1, choose the Settings command from the Options menu, and select the Don’t Break On Errors option. This will avoid the FatalExit prompt.
STATUS
Microsoft has confirmed this to be a problem in DB-Library version 4.20.00. This problem was corrected in DB-Library 4.20.50. For more information, please contact your primary support provider.
