I've been trying to paste George Somsel's index to the ECF into a Logos note file (plus, just to check, I've been trying the same with one or two of Steve's files). At first it works perfectly, then, after a couple of minutes, all the links just disappear. 
From an unrelated PC thread I picked up that the same thing seems to happen on PC when pasting from OpenOffice. So, since I'm using NeoOffice (which is based on OpenOffice) I'm assuming the underlying problem is the same. The PC folks found two workarounds: one involving L3, and one involving IE. Needless to say, I don't have L3 or IE. Nor do I have Word. And TextEdit won't keep the links at all.
As you can see I attached posts to both the above threads, but never received any help. Now I'm hoping you Mac folks can do better. 
Is this a bug in Logos, or a bug in the OpenOffice code that Logos can't do anything about?
Is there a workaround that works on Mac? For example: Steve could convert his file to one that could be opened in IE, and pasting from that obviously did work. Can George's file be converted to something that can be opened in Safari or Firefox, and will that make the links more 'stable'?
