Hello,
I’m using GtkRadiant 1.4.0 for mapping purposes… there’s a little problem I noticed yesterday.
After I created lightJuniors massively some of them lose the colour in the preview (but they are filled with the correct _light parameter in fact)… don’t know if it’s because cloning or it’s just typical radiant bug that I should not care about? 
It’s strange, doesn’t happen to every lightJunior and even after pressing enter to the _color and fade - (so the changes are applied and I can see that) - and opening the .map after reboot again some are affected with this trouble (probably random ones?). Checked using wordpad if the fields are O.K. and they do - so the compiler will treat them right, won’t it?
Greetings,
Igloo
** Edit: goldrush has the same thing (so it’s not only in my map, however I’d like to make sure if anybody knows it doesn’t do any harm or no effect to so many lights I created
