我用的是QQ 2006版本，原本安装以后用的好好的。但是今天我电脑挂在网上，QQ没有关。然后出去了一会，回来发现QQ没有先线。然后打开QQ，发现输入不了 密码。密码不能输入数字健，但是偶尔可以输入自己字母。但是我的密码是数字，所以输入字母没有意义。密码框这里有个密码锁，藤讯公司说这个锁是用来保护密码的。

卸了QQ2006，重新装QQ 2005SP1，发现还是老问题。
再卸了QQ2005SP1，装上QQ2005 beta1，用键盘还是输入不了密码。但是QQ带了一个软键盘，可以用鼠标输入密码。然而登陆不了服务器。

找了好多网站没有解决！希望大家HELP！！

不知道这个是不是楼上所说的日志文件？？
