Classicladder:4229: Gtk-CRITICAL **: IA__gtk_widget_get_parent:

[Hortensie]

Here are the steps I follow to reproduce the issue:

1.Set debug level to 3, load classic ladder with modbus
2. run linucnc from command line

This is what I expected to happen:

No Crtical errors in debug logs

This is what happened instead:

[c-morley]

Is that an actual problem with classicladder or is it just a scary sounding error message?

[Hortensie]

At least in my case classic ladder fail to establish modbus communication. I was wondering if this is a root cause or not.

[c-morley]

Pretty sure not as I can see the modbus error messages still complaining.

[Hortensie]

Right, I resolved modbus issue. If you think that Critical warning in debug logs can be ignored we can close this issue.

[c-morley]

Ok thanks for the update.
