I’m not familiar with the internals of IntelliJ IDEA and how tool window are handled in it but it feels like you can register a tool window only once but Cursive here is trying to register it more than once when two IntelliJ IDEA windows are created and shown one after another.

This seems to be an IntelliJ bug, new in 2023.2: https://youtrack.jetbrains.com/issue/IDEA-332621

ah, OK.

It’s possible I’m doing something wrong of course, and that a platform change exposed that.

Unfortunately I’ve never managed to reproduce it, and every time my IntelliJ restarts it has multiple projects open.

Yeah, the multi-window/project feature of IntelliJ IDEA has always felt like playing Russian roulette: sometimes, it opens those projects in multiple tabs in a single window; sometimes, in separate windows; and some other times, it flat out shows a dark, blank window for one of the projects.

Wait, so you have multiple projects on different monitors?

Yes

I wonder if that’s the issue, mine are always on the same monitor. I’ll try to reproduce with that.

One is Mac’s built-in screen and the other one is an external monitor.

Yep I can test that, I work on a laptop but mostly with the lid closed and an external monitor.

The thing is it’s difficult to tell for sure on which monitors IntelliJ IDEA decides to open those projects. 🎲

Hi, Colin. Following up on this issue, I think I found the steps to reproduce it. It turns out this can be reproduced in a single project and single monitor set-up (MacBook Pro’s built-in screen) as well: 0) start IntelliJ IDEA, if it’s not already running 1) ensure IntelliJ IDEA doesn’t automatically reopen projects when it starts up by unchecking the checkbox in the following screenshot. 2) restart IntelliJ IDEA 3) on the Welcome to IntelliJ IDEA splash screen, pick a recently opened project 4) you should get an error with the exception in the Notification tool window

Ok thanks Salam, I’ll see if I can repro with that information.

Just when I get the hang of quoting, we get previews back…

Thanks Colin! Downloaded EAP-8 and the test markers are back! I'm so grateful, this makes my life so much easier not having to switch back to IntelliJ 2021 every time I need to check why the tests fail!! 🙏 🙌 🙏 🙌 🙏 🙌 🙏 🙌 🙏 🙌

YES! Love you Colin! I can finally retire my "side-by-side" 2021.1.3 / 1.12.3 P.S. Download it from https://plugins.jetbrains.com/plugin/8090-cursive/versions/eap if you don't have "Check for EAP builds" under "Language and Frameworks > Clojure"
