SumatraPDF Plus 3.7.89

中文

OCR 文字与图片链接重叠时优先选字，避免单击、拖动选字误触整图跳转；图片空白处及普通文字链接保留跳转。
新增“定位当前章节”，可从目录顶部、查看菜单或命令面板清除筛选、展开并选中当前目录项，同时保持正文阅读位置。
缩小侧栏分隔条命中容差，避免抢占目录关闭按钮、搜索框与滚动条。
修复 PDF 中 Ctrl+触控板、远程桌面捏合或高精度滚轮缩放过快的问题（#123）。默认分级缩放现在累计滚轮 delta，每满 120 才跳一级，保留不足一格的余量。
保持普通滚轮每格一级的操作方式；正百分比缩放模式继续按 delta 大小计算。

下载 Windows x64 EXE。退出程序后替换安装目录中的 EXE，保留配置及配套文件。

Prefer OCR text selection over overlapping full-image links; preserve navigation from blank image areas and ordinary text links.
Add Locate Current Chapter to the TOC header, View menu, and command palette. Clear filters, reveal and select the current entry while preserving the reading position.
Narrow the sidebar splitter hit area so it no longer intercepts nearby buttons, search fields, and scrollbars.
Fix excessively fast PDF zoom with Ctrl+touchpad scrolling, remote desktop pinch gestures, and high-resolution wheels (#123). Default stepped zoom now accumulates wheel delta and advances one level per 120 units, preserving partial-notch input.
Retain one zoom level per normal wheel notch and delta-proportional behavior for positive ZoomIncrement settings.

Download the Windows x64 EXE. Close the application before replacing the EXE; retain settings and supporting files.
