My girlfriend is using MSN live and my custom emoticons are coming up about 1cm x 1cm. Much smaller that the original and impossible to tell what they are.

Parmesan doesn’t really have any control over the size of custom emoticons on the remote side – it just sends the images and lets the other client do what it likes with them. I know that the official client restricts the dimensions of custom emoticons (Parmesan doesn’t), but I’d expect that limit to be a bit bigger – maybe it’s a configuration setting in MSN live?
