Win7之家（ www.win7china.com）：Windows 7中的放大镜也存在Bug

 日前，来自澳大利亚网站Media Access Australia的Dr Scott Hollier发表文章称Windows 7中的放大镜对于视力有障碍的用户而言并不好用，很有可能是个“Bug”。

Hollier称此Bug出现在用户在高对比度颜色方案下使用放大镜全屏浏览时。似乎Windows 7中的放大镜在很大程度上要依赖Aero图形引擎，也就是说只有在Aero颜色方案下才能正常工作。而当用户切换到高对比度颜色方案，比如High Contrast Black时，放大镜就变成了旧版的样子。

而据Hollier所说，大多数视力障碍用户在使用全屏放大镜时都必须配合高对比度颜色方案，这对于成千上万名弱视用户而言，不得不说是个重大的bug。他们已经向微软发送了bug报告，等到微软发言人给出答复。

Dan Warne has tipped us off about a "bug" in Windows 7 for vision impaired people.Dr Scott Hollier of Media Access Australia wrote to APC mag to reveal the problem.

Hollier says "The bug occurs when a user tries to use the full screen Magnifier in combination with a high contrast colour scheme. The Magnifier appears to be largely dependent on the Aero graphics engine, meaning that it works well when Aero colour themes are used. However, when a user switches to a high contrast colour scheme such as High Contrast Black, the OS dumps the user back into the old Magnifier feature which, by default, shows a small magnification bar at the top of the screen."
