I can confirm this is still the case, four years on. Inline Hyperlinks works with the Glulx Entry Points (v.10/140425) that come bundled with Inform 7 but Flexible Windows requires a newer version of Glulx Entry Points which makes the links non-functional.
I’m trying my hand at debugging the problem but I’m not an Inform expert at all so I’m a babe in the woods here.
EDIT: So far I’ve ascertained the links are being generated consistently between versions but I think the behavior of some glulx functions have changed. Compatibility tests indicate:
- Glulxe Entry Points v.10/140425 (stock) — Inline Hyperlinks works!
- Glulxe Entry Points v.10/200602 — Inline Hyperlinks broken
Perhaps the problem was introduced when some of the extension’s functionality was delegated to Dannii Willis’ extensions?
