Bug 781653

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:15.0) Gecko/20100101 Firefox/15.0

Since OPENSUSE 11.4 + KDE4, mouse connected via USB hangs sporadically. This occurs apparently mainly during editing work, e.g. of mails in Thunderbird. Sometimes this happens also in other circumstances , e.g. during entering requested data in templates.I can still move the mouse pointer, but i cannot trigger any action with it, e.g. setting cursor or clicking on buttons or on close-, maximizing-, minimizing buttonds of opened applications. When error occurs during editing a mail, the text background is colored while moving the mouse pointer, but i am not able to activate the cursor again at the required test position. Any other manual activity still seems to be possible. I still can move select menue items by moving the up/down/left/right position keys. Further i can invoke the logoff/shutdown selection facility by ALT CNTL Del keys. This enables me to logoff the KDE session and re-logon. During logoff i receive a request to save edited content. The saving can be done also by moving the position keys accordingly. After logoff (not shutdown) and re-logon KDE4 the mouse is ok. This workaround works in the most cases, but in seldom cases data are still lost, when during logoff the text background is filled with color (means "delete it!).  Error didnt occur during OPENSUSE <= 11.3. I use VAIO VGN CS11S with NVIDIA drivers. Install of NVIDIA drivers from NVIDIS webside does not remove the error. During error, i also cannot use the "mouse substitute keys" at the laptop. Also using another USB connection doesn't help. I use DuaL Boot with Windows Vista. Error doesn't occur when working with Vista. Reproducible: Sometimes Steps to Reproduce: 1.I havent found a method to reproduce the error.

following happens:
1.) Mouse still ok. Cursor is at a specific location within the textfile.
2.) Error happens at this cursor position: When moving the cursor from 
this cursor position in forward or backward direction, the textline 
parts covered by the cursor movement (NOT the whole text!) are filled 
with a background color. In normal cases this happens if i press the 
left mouse button, just for copy and paste. 
3.) Beginning at this moment, it is not possible to localize the cursor 
at a different position.

I have found report #715932, which seems to describe a similar mouse problem.
