I've recently (3 weeks ago) updated slime from CVS, and now the M-. command no longer works for me.   I am no longer able to "drill-down" on the definition of a CLOS class, for example, and jump to the source file.  

I'm using SBCL 1.0.20 on x86.  I'm working with Weblocks source code if that matters.

This is was one of the features I used very frequently, and not having it is a serious handicap.  Any suggestions on how to make it work would be much appreciated.

Thanks,

Yarek
