question/bug: can't copy/cut & paste into or out of URI window

Version: 7.2
Platform:X11 on Mac OSX 10.2.4

I am unable to cut/paste/copy into or out of the URI/Open dialogue box 
at the top of the main amaya window. Also unable to cut/paste/copy into 
the attribute dialog box when completing an href. I used to be able to 
do this in the Windows version.

Any tips or is this a bug?

Thanks,

Danny
