App Version

All is in the title : I have the option : "Show confirmation dialog when closing the ComfyUI browser interface" selected in the settings of comfyUI desktop. But despite that it doesn't seem to give the wanted result.

Expected Behavior

A warning about process currently running AND unsaved works.

Actual Behavior

Nothing, it just close (dans weirdly, sometimes some process keep existing in the windows task manager ... )

Steps to Reproduce

Install a fresh comfyUI desktop, made a unsaved work, launch a process, close ComfyUI desktop.

Hi @msnbcorp! I'm Dosu and I’m helping the desktop team.

The confirmation dialog on close is not currently implemented in the ComfyUI Desktop app's main process, even though the setting exists and is enabled by default. The code only logs the close event and does not check or act on the confirmation dialog setting, so the app closes immediately without warning, regardless of unsaved work or running processes. This is a known issue, and there are reports of related problems like the app freezing or leaving processes running in the task manager. Some users have found that disabling the "Show confirmation when closing window" setting can help with freeze issues, but it won't enable a confirmation dialog—because that feature isn't wired up in the desktop app yet. For now, there is no workaround to get the confirmation dialog to appear on close in the desktop version.

@dosubot[bot] commented on GitHub (Feb 3, 2026):

Agreed—the fix should be pretty straightforward. Right now, the main process just logs the close event and doesn’t check the confirmation dialog setting or show any prompt, even though the Dialog API for custom dialogs is already in place and ready to use (reference, Dialog API PR).

To implement the confirmation dialog, you’d intercept the window’s close event, check if the setting is enabled, and call the dialog to ask the user for confirmation. If you want pointers to the relevant files or a quick outline of the logic, just let me know!

@desu, unfortunetly, i am not good with typescript, javascript etc, but you could point to the right parts and give a quick outline of the logic for others that want to work on the issue.

Hey, thanks for the report. I think I know why this is happening. The setting was probably added for the browser environment and doesn't cooperate well with the desktop Electron environment. So I'm working on a fix right now for that
