Xojo IDE hangs on save

StefanA · January 12, 2026, 6:32am

Has anyone else experienced Xojo freezing when saving since the last beta r3.1?
It just stays here and nothing happens:

We have never experienced this behaviour before.
It also happens after restarting the Mac.
Can only be closed using the “Force Quit…” function in MacOS.

Have you tried to sample Xojo from Activity Monitor?
What does it show?

StefanA · January 12, 2026, 9:41am

Nearly no activity.

Did you mean the analysis of the prozess?

Not much to see there. Some TCP sockets and auto release pools:

Yes, the exact same thing for me. It’s happened twice to me (once with each version for 2025 r3.1 beta). Also, has never happened to me before this version.

I let it sit for 15 minutes. There was no CPU activity during this time. I had other Xojo projects open that I was able to save and quit normally before finally force quitting Xojo.
I tried to recreate this issue, but was not successful. I’ve saved multiple times and ways before and after with no issues.
I save to my local Development folder which is not in the cloud.
Both times that this issue appeared, it was saving as a Xojo Project.
Fortunately I had run my program not too long before the lockup, so next time I started Xojo, I was able to restore the project.
I’m on a MacBook M4 Pro, running Tahoe (26.2)

Does this only happen in the .1 release?

Pete_Totushek1 · January 12, 2026, 4:51pm

The first time it showed up for me was in the .1 release. I saved many times in the 2025r3 with no issues.

Arnaud_N · January 12, 2026, 8:35pm

Hopefully the hangs happen before Xojo starts to overwrite the project!
(Having seen corrupted projects before, I assume Xojo doesn’t save to a temporary file prior to writing to the final file; but it wasn’t recently that I saw that so I might be wrong now).

Tim_Parnell · January 12, 2026, 8:54pm

Honestly, I do not care about that. Source control means you can roll back from a mis-written project.

I am far more concerned that the changes never make it to disk and are lost.

StefanA · January 13, 2026, 6:03am

I was able to reproduce it:
https://tracker.xojo.com/xojoinc/xojo/-/issues/80674

In my case I drag and dropped some windows into the IDE to check if this bug still exists that paths are written wrong ../../../../../..
https://tracker.xojo.com/xojoinc/xojo/-/issues/78891

After checking and confirming this bug still exists I deleted the windows again and saved the project → IDE hangs.

Tim_Parnell · January 13, 2026, 12:49pm

Javier confirmed on the ticket that this affects the public release. Can we move this thread to general so everyone is made aware their project may not save?

Amy_Barnes · January 13, 2026, 2:17pm

I co-sign this request, because I constantly hit the Save button when I’m coding, and this causes me concern.

Javier_Menendez · January 13, 2026, 4:13pm

Yeah, that bug even existed on previous releases.

Amy_Barnes · January 13, 2026, 4:18pm

I wonder which releases? I’ve not seen the issue with 2025r3 so far.

Thomas_Kaltschmidt · January 13, 2026, 5:01pm

I could reproduce it even with 2025r2.1, but only on Tahoe.

Tim_Parnell · January 13, 2026, 5:18pm

Ah, an important detail emerges!

Thomas_Kaltschmidt · January 13, 2026, 5:35pm

But i was wrong, sorry. Tried again and could reproduce on Sequoia 15.7.2, too. With 2025r3.1 and 2025r2.1.

Tim_Parnell · January 13, 2026, 5:36pm

This thread should really be public.

The issue affects release and previous versions.

Thomas_Kaltschmidt · January 13, 2026, 5:53pm

I have to say, i was not aware that this is even allowed.
