I would guess that this is a known issue and probably there is an open github issue on it.
But my quick look did not find it. So just in case.
I am running on a Windows 11 machine, with the last nightly build (0816).
I start up the IDE and have an open sketch. I go to the tab menue(...) and select the "New Tab" menu item and nothing happens the first time. No feedback, nothing. I then execute the command again and everything works fine.
Hello @KurtE - I am using Windows11, IDE 2.1.1 (stable build). I do not have an IDE >> TAB menu choice. For a new tab I use CTRL-SHIFT-N as well as the ellipsis (dots) and this is what I see...
Another interesting thing:
If I first bring up the tab menu, dismiss it, and then bring it up again, it works. So not sure if it is a timing issue, or maybe a problem with the first invocation of that menu.
Very close. IDE2 does not refresh menus as often as it used to, and it's a coincidence that the New Tab handler ID will be 0, which is falsy in JavaScript. See some additional findings here.
