>Something's wrong... I keep two tabs open, one for UT and one for C4u, and for a couple of days now I get both of them looking at C4u. Clicking Home opens the old login dialog of C4u, without the platform combo. Navigation to http://www.levelextreme.com/ (from a bookmark or by pasting the link into the address bar) takes me again to C4u, login without platform combo.

For now, the last platform selected is the one that is used.
