Not sure if this is a bug with Leopard or I'm being stupid (possibly the later) but... Has anyone else experienced this issue and do you know what is causing it? I am currently unable to send a file that has a space in the file name. The only change on my system that has occurred since I last sent and email in a similar way is I've updated my OS from 10.5.1 to 10.5.2. Any ideas how to fix it?
