One problem currently with the glype script is that it cannot process javascript well enough to allow every script on every site work, especially complicated scripts that are used to power mail programs such as GMail and Hotmail.
Hopefully, In future releases, fully working javascript processing will be integrated into the glype script which should allow javascript intensive sites like GMail to work.
The only current fix for now is to use mobile/html versions of the sites that do not fully work with glype.
I will look into making a plugin to redirect glype users to the HTML version of GMail and hotmail as a temporary fix.
