I know, save early, save often... but usually, nothing crashes anymore!
PD "server"(?) is still running, MIDI and audio work, and the windows I was working on are open, but I can't do anything (including "save") with the windows. I can drag them around, because that's my desktop manager not PD, and drop-down menus do drop down, but I can't close windows and - again - I can't save.
Any ideas before I lose my afternoon's work? I could screenshot, but most of the good stuff is in sub-patches.
I'm on Arch Linux, using XFCE4 desktop environment. The chance of someone responding before I reboot is very slim indeed.
