I've only noticed in the last couple of days that some objects are not loading. For instance, if I bring up the netserver-help.pd help file, the netclient object loads, but netserver doesn't. 

I also notice that some objects in iemmatrix do not load. For instance mtx_mul loads, but not mtx_mul~. Confusingly, the mtx_+ object in mtx+mul-help.pd doesn't load, but it does if I open mtx_add-help.pd.

I'm very confused. Can anyone enlighten me?

(For the record: I've deleted my .plist file and replaced the Pd-extended app with another fresh copy. No difference.)

Many thanks,
