Using Synaptics touchpad, set to use single-clicks instead of double-clicks.
Ubuntu 10.10 Maverick, 64-bit (clean install) on a Lenovo IdeaPad Y510
Single-clicks and tap-to-clicks register as double-clicks, and other weirdness

Often and randomly, the left-click and sometimes the tap-to-click will register double-clicks instead of single-clicks. This results in problems like closing tabs in browsers when clicking on them. Also affects drags, which horribly screws up text when trying to drag a chunk of text from one place to another in the document. At times just moving the mouse across a document will result in selecting text, despite the fact that no double-click occurred to actually select any text, and the unintentionally-selected text is then dragged or copied and pasted to some other part of the document.

Have also noticed that at times a single-click or tap-to-click results in something like two middle-clicks, or even a right-click and then the top-menu item. For instance, clicking on a tab in Chromium or Firefox doesn't simply select the tab, but instead opens two new tabs.

This is a new problem on Maverick; it's never happened in the past, and doesn't occur using Windows in a virtual machine. I've seen similar bug reports, but they're old and for regular mice, not for touchpads. I'm not sure what debugging info to offer since this is so random and doesn't result in an actual crash.
