So, I've finally figured out why the developers of roundcube just "don't" fix our problems. It's because they use FIREFOX!! For some unpeculiar reason, everything works on Firefox, and even has some other features when viewed on Firefox than any other browser, why is this?
Solution:
To RoundCube Developer(s): If you are going to develop a product that is mainstreamed to hundreds of people/companies, make sure it works correctly on all browsers. We are adults (or should be...), so take some responsibility for your product, or I can assure you it will go from good to bad.. really fast.
