Summary: Common smart indent macros windows flickers on scroll

Initial Comment:
The "Common smart indent macros" window appears to be redrawing improperly by 
repainting the area where the text input area is located with the text area 
background color inadvertently wiping the textarea out, then drawing the entire 
textbox on top of this repainted area, causing a flickering effect. This redraw 
of the entire textbox area is performed for each and every line scrolled.

To reproduce:

Open the "Program smart indent macros" window by going to Preferences -> 
Default Settings -> Auto Indent -> Program Smart Indent...

dropdown the Language Mode box and, unless you have another set of indent 
macros installed, I recommend you select C++, as its initialization code is 
fairly substantial.

Click the "Common / Shared Initialization..." button.

Scroll the textarea in the window that has just opened up and down relatively 
quickly, and observe the behavior I have described above.

@dav7:

I can't reproduce it either. Can you provide the output from 'nedit
-version' and can you try with the latest CVS version?

@John:

I can't reproduce it. Can you try it in a clean NEDIT_HOME env, i.e. make
new empty dir, cd into it, run 'NEDIT_HOME=$PWD nedit'.

Anyway, because you are using an unofficial version, you should report
such things to the 'distributor' (thats me in this case). Only if its
reproducible with official code, you should report it in this forum.

Thanks to both of you.
