Anyway, the following is not much better than other klduges and workarounds that I have found, except that it is at least reliable. What I do is use a recent tip for quickly creating notes via the terminal. I create an alias like this in my shell aliases file (mine is probably different than yours, so you will have to figure that out as it relates to your setup):
# simple note taking
alias note "echo `date +'%Y%m%d %H:%M - '` ${1} >> ~/Documents/notes.txt"
This allows me to quickly enter notes in the terminal like this:
note "enter note text here"So now the text is sitting in a text file in my documents directory. What I then do in Apple X11 is open a new Xterm window and enter this:
tail -f ~/Documents/notes.txt"I just leave that window open all the time. As I add stuff via notes/Aqua, the listing is updated dynamically in X11. So to copy and paste, I copy in Aqua, switch to terminal, paste as note, switch to X11, select the new text that has appeared in the Xterm window and center-click (your mouse may be different) to place the newly copied text into an Apple X11 window.
It shouldn't have to be this hard....
