Hi,

Thank you for your help on a previous post. I realize that in order to
access a widget, you need to use the lookup_widget function, I understand
how I am supposed to access it this way when I have a set such as ths:
Window
          |_ CList	- CList = lookup_widget(Window, "CList"); Assuming the
variables have been initialized, this works (Thanks to Andrae Muys)

However, in a new project I have set up it fails. I do not get any errors
but it crashes with a segmentation directly related to the lookup_widget
function. The widget tree looks like this:
winViewLogs
	     |_+dock1
	     |_+nbviewlogs
			|_scrolledwindow1
					 |_cl_bootlog
	No matter where I try the lookup_widget function to get a return poiinter
to any of the above widgets, I keep receiving a segmentation fault. I have
included the code as well, just to make sure if I was missing something. I
was able to isolate it to the lookup_widget function.

Any help would greatly be appreciated.

Thank you.
