I'm having a problem with Titanium 1.2.1 on Ubuntu. The problem was supposed to be fixed in this release, But it semi working.
For example. when i try to import KitchenSink it works great. but when i try to import my own projects it doesn't allow me to do it. So every time i need try a project i need to Create a new project, then copy the project and past it over the newly created one.
