For example, SyncWall, when you press escape the low shows:

```

and 10 is inserted at prompt. The same happens with nodelist viewer.

Does it only happen when mouse support is enabled for the user?

I don't have SyncWall installed myself, but when I tested this (with mouse enabled) and ran fileman.js, hitting ESC to exit doesn't do what you described, however some stuff is logged (in regards to re-enabling the default font I have configured in fonts.ini):

No. I disabled mouse support and it still happens.

Did you run fileman from xtrn menu or with ;EXEC ? (which doesn't work for me, I get !JavaScript fileman.js line 13: ReferenceError: uifc is not defined but that's a different issue)

I ran fileman.js from xtrn menu, configured like so:
```
Name fileman
Internal Code FILEMAN
Start-up Directory
Command Line %!jsexec%. -n fileman ansi
Clean-up Command Line
Execution Cost None
Access Requirements ANSI
Execution Requirements
Multiple Concurrent Users Yes
I/O Method Standard, No Echo
Native Executable Yes
```
But... running from jsexec might be very different from running scripts directly from sbbs. Do you have more examples/data?

Looks like it is related to the custom font stuff.

Interestingly, this issue does not happen with v3.20, so my guess is that it's related to Deuce's terminal abstraction stuff.
This looks really suspicious:
```
insert key into keybuf: 00 (\x00)
```
Re-assigning to Deuce to fix.
