The sqlite3-ruby gem was installed and the sqlite3.dll was correctly placed in C:\Ruby19\bin. I am not using Mongrel. Although MySQL is installed I am not using it for any of the tests. System tests were constructed in the c:\tmp directory as follows: ===begin== rails test01 cd test01 bundle install rails server ===end=== When browser is given http://localhost:3000/ the standard Welcome aboard screen displays. HOWEVER, when you click on the About your applications environment link Ruby.exe crashes intermittently with the following error information. ===begin=== ruby.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
