Recently various dialog windows started to deactivates (when adding a template etc.). It was already fixed for Edit summary - I have reported it as a bug (I dont know the number). Could you fix also other dialog boxes. E.g. for template in cs.wp:

1. Inserte - Template
2. comes up the dialog window and deactivates itself (i.e. you cannot start to write directly)
3. you have to use the mouse to click into a dialog box to activate it
4. add data and safe

Actuall behaviour is prety annoying.
