i am having troubles with QGIS 2.6.1. It crashes when i try to change the symbol selector within each vector layer. If it doesnt crash it seems that the changes i have made in symbol selector do not display. see screen shot below for more info.
crash error message: qgis-bin.exe has stopped working. a problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.
