[PD] pd-extended keeps losing track of extras

[oli_kester]

Hi all, 

I just recently started learning Pd, and it's great!

One problem I keep running into is pd-extended seeming to lose track of the extra libraries. This can happen for just a few objects, or for many at once. 

For example, this morning when I opened my patch from yesterday, the "aenv~" object had a red dotted box around it (i.e. it couldn't be resolved) - and creating any new "aenv~" atoms gave the "couldn't create" error. I went to bsaylor/aenv~-help in the help browser, and in that patch the "aenv~" had been created properly. I was able to copy the atom into my own patch, and now I can create "aenv~"s again... 

Yesterday I even managed to find it impossible to create a "dac~". This has happened about five times now, and seems to usually be resolved by restarting the whole program. Although this most recent issue with the "aenv~" object seems to be sticking around :( 

Would anyone have any ideas about how this could be resolved?

I'm using pd-extended 0.43.4 on 64-bit Xubuntu 14.04 LTS. This isn't to do with the issues pd-extended has running on 64-bit Linux is it?

Thanks, 

Oliver
