CMO crashes when loading scenarios

Re: CMO crashes when loading scenarios
Re: CMO crashes when loading scenarios
This tutorial has a starting message that interferes with the settings scenario window, that may remain in the background. This is a glitch in CMO.
So you do not have time to click on Begin scenario?
Try the Standalone, A helping hand, can you click on Begin scenario?

I have no time to click on Begin scenario but the Standalone A Helping hand works just fine. I think the problem is with the starting message.Nikel wrote: Sun Jun 07, 2026 9:53 am This tutorial has a starting message that interferes with the settings scenario window, that may remain in the background.

Re: CMO crashes when loading scenarios
Good news then
But you commented in the first post, that it happened in any scenario.
The new Command.ini is what has changed this?
Or all the scenarios you tried has a starting message?

Re: CMO crashes when loading scenarios
Yep, at first I thought its in every scenario, but I think the problem only appears while loading tutorial scenarios. In some tutorials I can be fast enough to click on begin scenario and then everything works fine.Nikel wrote: Sun Jun 07, 2026 10:11 am Good news then![]()

Re: CMO crashes when loading scenarios
Have you enabled Log debug information into a file and checked the ExceptionLog?

Also, enter editor mode (on startup just click on create new scenario, then open the tutorial again.
If that doesn't work, it's probably a problem with LOADDOC function

Re: CMO crashes when loading scenarios
Umm, I have the same problem. I've tried to edit .scen/.ini of tutorial to avoid LOADDOC and failed. It occured when pass the side selection. We both use Windows 11 referred to Lukano's log. It might be something wrong with webview2 & Windows11.
Re: CMO crashes when loading scenarios
Try with this scenario, the same tutorial with the first message, when the scenario starts, removed.
The second message should appear 10 seconds later, not removed.

Re: CMO crashes when loading scenarios
Then, it is not a starting message what causes the problem? What happens with that scenario, still CTD when you load it, or now happens 10’ later when the second message appears?
Also what happens in your case with A helping hand scenario?

Scenario A Helping Hand works well but CMO's graphic interface regularly freezes when start/resume the scenatrio.
I also tried another method of editing Autosave_20sec.scen to enter FlightTutorial 1. The method itself works, but interface freezes until the next message pops up to pause the scenario. If start/resume is pressed again, the graphic interface will still freeze.
Re: CMO crashes when loading scenarios
Perhaps you can record a video for the devs.
Microsoft Edge/Webview is updated in your case?

Time was jumping from 8:00:05 ~ 8:00:09 ~8:00:15
Re: CMO crashes when loading scenarios
It freezes when you select a unit?
What happens if you close the right panel before selecting a unit?
