** Using WeBWorK **

This is a general question about Perl warnings in WeBWorK 2. Are other people out there running their Apache server with PerlWarn turned on? And, if so, do you find that this results in some warnings being kicked out by WeBWorK 2?

My habit is to run everything with full warnings going, and so my default server configuration includes setting PerlWarn On. However, this results in a number of uninitialized value warnings from WeBWorK 2. The most conspicuous of these is on starting the Apache server; this error is reproduced below, and appears to be caused by no course being defined when the server starts. (I get this error echoed to the console from which the server is started.)

Thanks, Gavin
