Re: [ptp-dev] Event messages not being freed by proxy

Greg
I'm still seeing the problem with a null pointer exception when creating
new resource managers. Rolf is also seeing it now that he's just getting
started with the GUI work for his LoadLeveler plugin.

Re: [ptp-dev] Event messages not being freed by proxy

Regarding the other problem when creating a new RM. I'm not able to
reproduce what you're seeing, even when I create a new workspace. I
wonder if there's a preference problem or something. I'll keep trying...
