'End app' closes all my subapps

[Tiny]

Build 249, MMF dev.

Two questions:
1. Can a project become "semi corrupt" so events start acting differently and effect other objects?
2. Anyone else experienced this?

The set up:
I have 17 apps setup in a project. I've been at it for years as some of you know and this particular situation has not occurred before. All of a sudden the 'end application' for one subapp closes all my subapps!

In short, this is the "flow" of things:
The project app (main app) starts a subapp.
In this subapp is another subapp. When this second sub is closed with 'end application' (in it's own column) the first sub is also closed and I end up in main app.

I don't think there is a solution to it just wanted to check if someone else have encountered it.

I am worried I will have to redo the project.

Are you sure there isn't an event that closes the intermediate sub-app for some reason (modified global value, etc). Maybe in a behavior or in global events and you forgot it?

If not, if you can send me your application I'll put a break point in the End Application routine and perhaps I can tell you what happens.

Thanks Yves, I'll check it again before sending it to you, it's big.

There are lots of 'close' and 'open' instructions sent through shared data object so something may be "cross contaminated". I don't have any global events though.
I'll go back to a previous backup where it still worked and redo the last changes plus be more aware on what I'm doing.

Got more strange things happening so I reinstalled MMF. It 's probably due to a windows freeze a while back while MMF was running.
Works fine now.
