Chrome error in dev tools console whilst using mdemo.dll

[Wicket]

Hi all,

This could of been here a long time, but I've only just noticed....It seems to be chrome only.

If you open google chrome dev tools (F12) and then load up the desktop demo from here - http://prime.fmsoft.net/demo/desktop/mdemo.dll

All seems fine, however if you refresh/reload you get the below error.

I believe UniGUI used to show a 'Are you sure you want to leave dialog of some sort'? I can't be a 100% on that though.

Has anyone got an explanation for this?

Doesn't seem to cause an issue....just looks really bad...

Error from console is below....

Hello,

I didn't get such an error. What version of chrome are you using?

@Sherzod Sorry - should of added this detail to my post. 

Chrome version is: Version 108.0.5359.124 (Official Build) (x86_64) on macOS

edit - google chrome says it’s the latest build.

Also, I’ve checked live projects I have and this issue is also present on those live projects.
