I am running winxp 64-bit in a virtual machine using parallels 5. On the virtual machine, I'm building and debugging GUI code. In the application I'm debugging, a left mouse button click on a widget is invoking *two* events instead of *one*, so any callback method associated with the widget is called twice. The mouse pad is correctly generating one event per widget-click. Can anyone recommend a way to get the mouse to behave as expected? I'd like to be able to use it. Things of note: My (usb) mouse is associated with the MacOS (associating it instead to the virtual machine causes the cursor to not be displayed). thanks, wen
