AltoRetrato / IMDb 'My Movies' enhancer

Whenever I refresh my ratings/lists, I find that it leaves out some of my custom colours. For example, I have my ratings, plus a list of films on iCM and a list of films that aren't. When I refresh it often just highlights the titles as 'appearing on a list' with the bold blue, then I refresh again and it'll be the bold blue + green for rated films. I usually have to uninstall and reinstall the script for it to take into account all the lists again.

This looks more like a connection problem than a script problem (but I could be wrong). It would be interesting if you could open the Javascript console ([Ctrl]+[Shift]+[J]) and note if there are any errors or warnings there. If you find any, please share them here.
