Forms 6i to 11g questions

I am at a client site where they are upgrading forms 6i to 11g. They are having a couple of issues that I was hoping I could get help on:

1. Is there a utility to convert an icon file (.ico) to a gif file? The problem the customer is having is they can convert the file, but the size is changed. They need the icons exactly converted to a gif file.
2. Is there a way in forms that when you resize the screen, will it make the items bigger and smaller?
3. For the migration tool, there seems to be an issue where it loses color (items) and sizing (canvas). Is this a known bug or if there is a setting to fix this?
