Hi All, After using Transmission for a while today, I'd to reboot, after reboot when I went to launch Transmission from the dock again instead of launching, the icon had a question mark appear on it. This previously happened with MSN Messenger too. I know that this means it can't find the application, but why is it happening? In the case of transmission, I binned the dock icon, opened applications and put a new link into the dock from there. So the application was still in the exact same place, yet OSX is telling me it wasn't?! How come this is (randomly) happening, and what is the solution? Cheers Also, the Safari dock shortcut was missing this morning, though the application was there as always, why would that have happened? Noone? I had Grab in the dock until today, went to open it and the question mark sign came up so I dragged it to the trash. Went to applications and utilities and there's no sign of Grab, nor is it in the trash, despite me not having emptied the trash can. What is going on?
