Sure thing. Is the client running in a window? If it's running as a cow icon in the Windows taskbar, double-click on it to bring it up in a window.
If you see stuff like this:
[May 29 21:23:35 UTC] Loaded RC5 32*2^28 packet 33A78248:70000000
then it's doing RC5. If you see something about OGR stubs, it's doing OGR.
To change the client to run just one or the other, edit your dnetc.ini file. For example,
project-priority=RC5,OGR=0,CSC,DES would make it so the client will only do RC5. <--edited an error, doh!
