I use html documents to present my notes for a dance in a CSDS frame. 
I also usually use the split-screen option to show 2 frames side by side. 
I also want to be able to edit the source html of the notes file 
during the dance to record what I did tip to tip.

 For one dance if the notes document is displayed in the left frame 
and I right-click and select "Edit source", I get an error message: 
"Empty pathname for frame 0". It doesn't happen every time, but quite often. 
The error message never appears if the notes document is displayed 
in the right frame and I do the same operation. But whichever frame 
it's displayed in, if I get past the error message the edit window comes up, 
but I can't actually edit anything. It seems to be in a view mode only. 
If I right-click in the frame and select "Open with" instead of 
"Edit source" I can bring it up in Notepad and make changes. However, 
the changes are not immediately reflected in the display when I finish the edit. 
I have to exit the dance and go back into it.

 I have this setup for several dances, but it's only this one that I'm having 
trouble with, the others behave as I expect. Any idea what might be going on??
