So I may have found a fix for my issue above, I opened properties and clicked on Run as Administrator AND clicked on Change high DPI settings then checked the "Use this setting to fix scaling problems for this program instead of the one in Settings. That's it, I only checked the two setting in the programs properties tab on the desktop. Before just as soon as I would click on the change Zoom in OR the multi window bug would pop up, at first I thought it might be the mouse as OzHybrid suggested....Nope, new drivers didnt fix anything, then tried compatability to Win8...nope again. After clicking on the two boxes in the picture below I believe my issue might be tied to the High DPI scaling setting. Its late so I cant play with the program tonight to see if it breaks but hopefully tomorrow.

Edit: had to play with it...messed with it for about 30 minutes, no issues so far too bad its taken me this long to find the possible issue.

Thanks for your report, much appreciated! This will surely help other users. It's unfortunate that we have not found a way yet to fix it natively... Also very annoying that the dev team can not recreate the bug on our machines, so it's a shot in the dark to fix it.

Interesting. Lately we have been getting reports that simply running as administrator is sufficient to solve the problem. Did you confirm if the problem still exists if you Run as Administrator *without* the High DPI setting change?

At this point I'm just happy that there seems to be a workaround because this problem has confounded us (most likely it does not originate in our code but it is still our problem).

I did not Neil, but now that I have something that works, I can play with it a bit to see if its one or the other, or both that fixed the isdue.
 
Thanks, I look forward to your report. In the meantime I'm very glad you have it working again and didn't have to go back to 15.03. :)
Me too, I have a 60lb rocket to sim for SodBlasterVI and was worried I wasnt going to be able to do it before launch day and I only have 4 evenings left to get everything ready before then.

Went back and disabled the DPI scaling and ran just as an administrator permissions and it still worked fine.

Windows has over the last few years also reduced the permissions an administrator gets allocated to create super administrator categories.
You thought you were an admin but now you're a lesser admin....

That may well be true, usually my "account" (the only one on the machine) is set to run as administrator.

Maybe its recommended for everyone running Windows and having issues to set the program to run as administrator.

The GUI framework that OR uses is quite old and hasn't really been kept up-to-date (not that there are a lot of good choices out there with Java0, so I wouldn't be surprised if it had something to do with the dpi scaling.
 
If someone is experiencing the Windows GUI bug, and has experience with running a JAR file from the command line, could you please try running the JAR file with the command
Code:
java -jar -Dsun.java2d.uiScale=1 OpenRocket-23.09.jar

If that resolves the issue, we can ship the packaged installer with this JVM by default, so the issue is "fixed" natively.

I've been using 15.03 on my Win10 laptop for years. Was using it today, closed out of it for a couple hours, tried to open later, and wouldn't go beyond the splash screen. Rebooted, nothing. Removed that and installed the newest version, same issue. Any ideas?

Anything anyone says is a guess. You've not provided any of your computer info or system configuration.
But my guess is Windows updated something without telling you and has messed something up in the background. Doesn't want to work with Java because it sees it as a security risk? Your Antivirus won't let it do what it needs to? Check that for history and see what it's blocked in last 24 hours.

Are all your drivers up-to-date?

run as administrator and see if that fixes it.

It's a 2015 HP x360, i7-5500U. Windows 10 version 22H2. No antivirus blockage. It said the last Windows update was several weeks ago. There was one available, so I went ahead and installed it to see if it would help, but it didn't.

There was one not up to date, but it was from a few years ago. I installed it anyway to see if it would help, but it didn't.

run as administrator and see if that fixes it.

I tried that, but it didn't help.

I think I may just do a clean re-install of Windows.
