更新：请忽略我下面的长篇大论，快速解决方案是：停止 PT 并重新启动
我刚从出差回来，所以有几周没打开 PT 了。在这种时刻，你往往会注意到一些平时忽略的问题。
今天早上我发现，我无法“正常”使用鼠标滚轮来滚动本地翻译草稿或资源：
鼠标滚轮的每一小格转动，效果大约相当于在键盘上按了一次“向下（或向上）翻页”。换句话说，内容移动的距离非常大。
在其他所有工具中，我的鼠标滚轮工作正常。例如在这个基于浏览器的论坛编辑器中就是如此。所以你可以想象，我已经习惯了滚动时内容自然上下移动。在 PT 中强迫自己只转动滚轮一小格是非常困难的。
我再次检查了鼠标设置，并在其他编辑器中进行了测试：在那里，滚轮的表现符合预期，每次微点击大约移动一两行。
我甚至一度怀疑是我的鼠标有问题（真丢人）（因为它是一个 Kensington 轨迹球）。于是，我拿了一个非常主流的老式 Logitech 光学鼠标，结果在 PT 和其他工具中表现完全一样：其他工具工作正常，而 PT 在每次微点击时都会剧烈跳动。
我还搜索了 PT 的设置，看是否有滚动相关的配置。有很多关于滚动的帮助条目（因为同步滚动非常重要……）。当我搜索“mouse wheel”时，我被带到了键盘快捷键页面，但在那里我找不到任何关于如何让 PT 温和处理滚轮、每次微点击只移动一两行而不是整个窗口的条目。
在电脑前度过了这么多年，许多操作已经成了我的一部分，比如使用许多键盘快捷键、在工具之间切换、滚动等。因此，有一个工具在某一方面表现明显不同 是一个挑战；也许你能理解。
这感觉像个 bug，但我总是喜欢先在论坛里问问，再提交像 bug 报告或新功能请求这样“严重”的东西。
感谢任何输入。

Update: Skip all my text, quick solution: stop PT and re-launch
I just came back from some travel, so have been off PT for a few weeks. In such moments, you notice things.
This morning I noticed that I cannot “normally” use my mouse wheel to scroll through local translation drafts nor through resources:
Each tiny tick of my mouse wheel produces roughly the equivalent of hitting “the one-screen-down (or up)” on my keyboard. In other words, it moves the content a lot.
In all other tools, my mouse wheel behaves normally. For example here in this browser-based forum-editor. So you can imagine, that I am used to just rolling and the content would naturally move up or down. It is very hard to force myself to give the wheel just one tiny tick in PT.
So I double checked my settings for the mouse and checked in other editors: There the wheel behaves as expected, about one or two lines per mini-click.
I even doubted my mouse (shame) for a moment (because it is a Kensington trackball). So I grabbed a totally mainstream good ole optical Logitech mouse, and had exactly the same behaviour, both in PT and in my other tools: Others work well, PT jerks on each mini-tick.
I also searched through PT settings, if there is a configuration for scrolling. There are many help-entries about scrolling (as it is so important to scroll in synch…). And when I search for “mouse wheel” I get taken to the keyboard shortcuts, but in there could not find any entry on how to tell PT to take it easy with the scroll wheel and give me one or two lines rather than an entire window per mini-tick.
After so many years on a computer, there are many manipulations that have become part of me, like using many keyboard-shortcuts, toggling between tools, scrolling. So having one tool that behaves distinctly different in one aspect is a challenge; maybe you can understand.
Feels like a bug, but I always like to ask in a forum, before submitting anything as drastic as a bug-report or new feature-request.
Thank you for any input.
