Helo, Sorry, but I am experiencing some problems trying to use the Oberon System 3 (Release 2.3) on a Thinkpad 600 equiped with Windows 2000 (service pack 3). There is happening a misfunctioning with the mouse 3 buttons emulation schemme (as I am using a traditional mouse with 2 buttons). When I press CTRL + left botton of the mouse, the screens continuously blinks. I can not move, resize or use Copy & Paste facilities. I allready have tried to find documents over the install directories or via internet but I am not successfull. I will apreciate a lot if someone can get me some help (maybe the solution is quite simples as edit a configuration Text file - but how?), thanks in advance Fernando ps: could be the problem be related with mouse driver for IBM/Thinkpad? .............................
