Hi, I have a problem since i changed my machine to a new laptop.... In the old one i was able to use the ctrl+alt+up/down... to select columns. In this new one it seems it doesn't work...i can do the same with the middle button of the mouse though
wow, I just fixed... it was the Intel(R) HD Graphic driver for windows 7. It seems to hook to those keys.but it is easy to disable, go to Graphics Options > Hot keys > Disable hot keys.
