QtCreator ignores changes in newly added qml file

Hello everyone, I am using QtCreator 2.4.1, based on Qt 4.7.4, on Ubuntu 64 Bit on a Virtual Machine (VirtualBox). I am using a qrc-file to keep track of my qmls. When I add a new qml file to my project, QtCreator should copy it to the build directory whenever I build the project and my new file has changed, but that does not happen unless I change another qml file as well or do a rebuild. What must I do to make QtCreator check my newly added qml file for changes whenever I hit the build button? Sometimes I am able to avoid this problem by adding the file to the qrc-list by hand instead of using QtCreator’s menu, but it doesn’t work everytime. Alex
