I'm using Parallels for Mac (Build 7.0.15098) and a guest Ubuntu 12.04. I use a Wacom Bamboo Pen & Touch (CTH-460) as my only mouse device. The touch part works reasonably (although the cursor moves a LOT quicker under the guest OS), but the Pen part doesn't work properly at all. I can hover the pen above the tablet to move the cursor ok, but if I tap the pen on the tablet the guest OS will register a click and a drag to a random position on the screen. It happens the same in VMware Fusion 4 (both with fresh installed of the guest OS). If I force the USB device to connect to the guest OS I lose the usage of it in Mac OSX but then the tablet works fine under Ubuntu. Is there any fix for this? I couldn't find any advice on the forum, just others with tablet issues.
