ดาวน์โหลด KillerPDF 1.6.3

A bugfix release for the 1.6 line. Highlights: memory use on large documents is dramatically lower, and two save corruption bugs (crop boxes and bookmarks) are fixed for good, including healing files damaged by earlier 1.6.x builds.
Changed
- Links open directly again: the confirm-before-opening prompt and its Settings row are off for now.
- When both document scrollbars are visible, the vertical bar now runs the full pane height and owns the corner.
- Grid view packs pages edge to edge with a hairline separator, so more of the window shows actual pages.
- Two-Page mode: Fit Page now leaves even margins above and below the spread.
Fixed
- Saving any PDF whose pages had no crop box silently planted a zero-size /CropBox on every page, which Adobe rejects with a "page dimensions out-of-range" error - the real reason merged Google Docs exports failed in Acrobat but opened in Chrome. Every save now strips degenerate crop boxes, so re-saving a file damaged by 1.6.x heals it (thanks Richard Lam).
- Saving any PDF that has no bookmarks silently corrupted the file's structure (a dangling /Outlines reference). Strict viewers refused the file with a repair prompt, and the repair stripped fillable forms. Saves are now clean, and the repair path first tries a lossless PDFium re-save that preserves forms and bookmarks, so files damaged by older builds recover intact (#103, thanks Peter5164).
- High memory use on large documents (#122, thanks RoyYang567): the page-bitmap cache is capped to a window around the viewport, closing a tab returns memory to the OS, and Continuous view only holds bitmaps for pages near the viewport - a 243-page image-heavy PDF now costs a few hundred MB instead of climbing past 7 GB.
- Switching from Grid to Continuous view kept the grid's scrollbar overrides, clipping zoomed pages with no horizontal scrollbar.
- Closing with unsaved changes stacked two prompts; confirming "close without saving" now counts as the quit confirmation, and it defaults to No so a stray Enter can't discard work.
- The quit prompt no longer appears when no documents are open.
- Two-Page mode: arrow keys, PgUp/PgDn, and the wheel's edge page-flip now move one spread at a time (#120, thanks eddardburger).
- Selection boxes could get stranded on screen until restart; they are now removed properly and swept on file close (#121, thanks TaBnLd).
