Hi Romain, I just downloaded a Squeak3.7b-5868 image from uiuc, opened it, clicked on the desktop to get the World Menu, selected 'open...', then 'morphic project' and a Project Window appeared on the desktop.

Now if you click on the 'Unnamed1' label at the bottom of the project window you get the following walkback:

Hi Hernán,

Your fix seems to preserve the behavior of the selection, but I have been unable to produce the bug ... Could you tell me how to reproduce it ?

Thanks, Romain

Hi,

Poking a little I found that the problem is on TextMorph>>keyboardFocusChange: first line:

paragraph focused: aBoolean

Which was added on 5849TextMorphSelectionFix-rr

I read on TextMorph>>paragraph's comment that paragraph

instantiation

...

is lazy so I think that we should use here the getter instead of

accesing

...

directly to the variable. Attached is my proposed fix but please someone review it first because I know nothing of TextMorphs.
