I am running woody + sid (for KDE) on a laptop with a touchpad and a USB connector. I have noticed that when I plug a wheel Logitech mouse to the USB connector the cursor behaves, sometimes (not constantly), in an unpredictable way for some KDE applications. This is most frequent when using kbabel ( I have real problems when translating big paragraphs because the cursor jumps forth, or the application moves some fields forth or back), less frecuent when using Kmail (for example), and very rare when I use konsole. I have not tried this with non-KDE applications.
If I use this same mouse (with a USB to PS/2 interface) plugged into the PS/2 port the applications are rock stable and the cursor always behaves as it should. Has somebody experienced this same behaviour?, Is this KDE related, X related, USB related or specific of my laptop?. Is this a known bug?. I am lost. thanks, Pablo de Vicente.
