SpiderBasic

When I try to run any example, either from C:\ or C:\Program Files, I got the following error:

The web page at http://127.0.0.1:9080/SpiderBasic_Compilation0.html might be temporarily down or it may have moved permanently to a new web address.
ERR_UNSAFE_REDIRECT

When I copy the code, save it somewhere else, it works. All examples seem to always be loaded from ProgramData? Can it be that working in this folder causes problems?

do you run it from IDE pressing F5 ?

Yes

sb run a localwebserver (aka 127.0.0.1) maybe your antivirus/firewall block it ?
can you try turn off them ?

I have none. It works if I copy paste the code into a new file, saved on the desktop, but not as a new unsaved file.
