Cannot move a LyX file to another Folder

[Vilaça Olivier]

Hello,

I have a weird problem. I created a LyX file on my Desktop and it is  
impossible to move it to another Folder (I use Lyx 1.5.6 with Mac Os X  
Leopard 10.5.5).

I tried to move it, to copy it, to open it in Lyx and to save it to  
another Folder, to copy the content to a new LyX file and to save to  
another Folder, but any option I try gives my the same result: I can  
open LyX and then open the file, but I cannot open the file in LyX  
through directly clicking on the file. Each time I try this, LyX  
crashes and close.

Is it due to the fact that I have included figures in my file? How can  
I solve that?

Thanks in advance,
Olivier
