When I am typing, my mouse cursor, if left on the text, will eventually auto-click in whatever space in the the text box I happen to be, causing me to type in the middle of a sentence. Also, the cursor in the text box will frequently stop mid-word and the screen will scroll down all of a sudden when pressing the space bar while typing. My question is, how do I change this behavior because it is driving me absolutely bat crap crazy. I have an Acer Aspire One D257 Netbook. I am not sure if it's a Xubuntu problem because it does this while I am using Windows 7 too. Any help would be nice, thanks!
It sounds like your hands get too close to the touchpad when you type, accidentally triggering mouse clicks. In the settings for the mouse and touchpad, there's a setting for deactivating the touchpad while typing; make sure that one is checked.
You may wish to try the program called GPointingDeviceSettings. It allows you to deactivate clicking by tapping the touchpad. It's in the repositories, so you can just follow http://apt.ubuntu.com/p/gpointing-device-settings to install it.
