I have a web dialogue which works fine on Mac, including opening a Help page in the same (standard SU location) folder as the dialogue page.
Testing it on Windows ran into several problems, now solved, about getting the built in IE module to open the dialogue page in the right version of IE. But when I click on the link to open a Help html page in the same folder, the page doesn’t open.
Trying the web dialogue directly in IE on Win 7, and with the F12 Developer tools showing Console or Debugger, I see there is an Access Denied message.
The plugin is installed as usual in the standard SU Plugins folder, in
\Users\<username>\AppData\Roaming\Sketchup\Sketchup 2016\Sketchup\Plugins\<plugin name>
What might be causing this? The web dialogue html page includes the first line
<!-- saved from url=(0014)about:internet -->
to avoid problems of sandboxing local files in IE.
The dialogue page opens fine when loaded into Chrome, and the help page link works from there. The Close button on the Help page reopens (as designed) the web dialogue page.
If I try to load the web dialogue page directly into either IE or Firefox, the former opens the page, then overlays it immediately with an error page saying “The webpage cannot be opened” complaining that it can’t understand the skp: protocol. Firefox just displays a similar error immediately, without showing the web dialogue page. Neither says Access denied.
What can I do to get round this?
