If you use an ampersand (&) in the game Title field, it doesn't work properly.
To reproduce:
1. Add a game - let's say the file is called "FireandIce.lha"
2. Rename the game Title to "Fire & Ice" and click Save Changes.
3. The title of the game underneath the joystick image (and above Play Count) will revert to "FireandIce", although the game's disk tile on the right will display the renamed title "Fire & Ice".
4. Click on any other game tile - let's say "Turrican". The details on the left will switch to that game as normal.
5. Click back on "Fire & Ice". The game details on the left (Title, Play Count and Play Time) will still display Turrican's details - but strangely the image above will be from "Fire & Ice" (be that a joystick image or a screenshot if you took one).
6. You can still edit "Fire & Ice" if you have the game tile selected (even though at the moment it will be showing Turrican's details).
Hopefully this makes sense! Have a play and you will see what I mean.
