Since 23/04/2006 I am waiting for the promised solution... http://forum.parallels.com/archive/index.php/t-951.html Release 2204 was launched and nothing. With parallels mouse sync tool installed - no whell, no third bottom and even no any mouse bottom or pointer operational in win-os2. Please, is there any specific mouse driver that could be installed, at least for Windows 3.x as a workaround? Without mouse wheel I can work but without any mouse operation not! RS37
