Has anyone seen a dialog like this related to Xojo-to-Javascript bridging? It’s popping up in response to a callback to Xojo from a HTMLViewer. To be clear, this is not my dialog. I’ve never seen it before.
Behavior on a Mac works as expected (no dialog, and the callback triggers a new window) but on Windows all I see is the dialog and the expected new window is never created. The app then crashes hard several seconds later.
I’m wondering whether this is some kind of internal debugging popup, and if so, if anyone knows anything about why it’s appearing and what kind of underlying error might be triggering it.
My callback passes back two string params.
window.executeInXojoSync("viewRawData", JSON.stringify(data, null, " "));
The second of which can be quite big (100-200k). I couldn’t find any documentation of a size limit for callback params – has anyone run into issues sending large amounts of data across the bridge on Windows?
More context:
- Xojo 2025r1.1.
- Occurs while remote debugging on UTM-emulated Windows 11 (Xojo running on a Mac). Running the app on the Mac works fine.
- WebKit-based HTMLViewer (app still using API 1) is running a preact-based local web page. Page is entirely self-contained and has no external links.
- Callback to Xojo is triggered by a button click within the web page.
