If you wrote the application that you're using with the ODBC-ODBC Bridge, check your code. Applications generate access violations by passing invalid pointers to the ODBC APIs.
On older versions of Windows, Dr Watson runs when a program fails (note that installing other software, for example, Microsoft Developer Studio can change the spawned debugger). This program writes information about your operating system and the program that failed into a log file. It shows the threads, where each of them was when the program failed, and which thread caused the problem. This file can help you determine the source of the problem. The Dr Watson log file is %WINDIR%\DRWTSN32.LOG
