My rebuild of Qt6.9.3 should have eliminated the calibre Open With issue. Kovid's work may have made my fix unnecessary, but still...
By the way: I'd appreciate it if those who build their own Sigil on Windows could verify that they're able to successfully launch Sigil by right-clicking on an epub and selecting Open With->Sigil from the context menu.
Until this commit last night (
https://github.com/Sigil-Ebook/Sigil...a54bf57f31af17) Sigil was silently crashing for me on Windows 10/11 when trying it. The Event Viewer would show a crash related to Qt6WebEngineCore.dll. This was only when building Sigil with Qt6.9+. It worked fine with Qt6.8.2
After the commit, I've had success launching Sigil in every way I can think of: shortcut; double-clicking an epub; right-clicking an epub and selecting Open With->Sigil from the context menu; dragging an epub and dropping it on the Sigil shortcut; from the command line (with and without an epub as a parameter).
Sorry to potentially derail the thread.
