On a MacBook, I got a new HDD an installed Windows 7 on it and Ubuntu as dual boot.
I can right click in Ubuntu using the 3 fingers gestures - but I can't do that in Windows 7
I know this is a stupid question, is there any way to fix this?
It's not a stupid question.
From the BootCamp Readme:
To right-click using a trackpad:
Place two fingers on the trackpad and click the trackpad button.
You can also use the keyboard: ShiftF10. Of course, for that to work, you need focus to be on the control or link for which you want to see the content menu, which isn't always possible. So it depends on what you're right-clicking.
Generally, command-clicking is the old way of right-clicking. Not sure if that continues to hold true in a win7 install on the mac platform though.
