@romit In BAS 0, this is not a tab, but as it were, the initial page of the browser and it cannot be closed, only the following can be.
If 0 close it, then the stream itself closes as it were :)
The browser seems to be closed.
@FastSpace The a/m error is from a desktop of mine, in the same LAN, and I'm connecting to it via RDP with my laptop.
Could this be because there is no actual display attached to the computer?
Updated version of BAS - 23.2.1 solved most of the issues I had.
I opened backup version of project file in text editor and rebuild
it in new BAS version 23.2.1.
