Specifically, the Dialog Box headers are different.
When viewing via the Editor preview, you are able to see the #POPUP line being rendered as a Dialog Box header. (this is what I would expect).
However, in game, the line is ignored for Decision events (decision.txt).

#NAME= DE 603 - Germany: Entice Franco To Enter The War? (AI - 25% Yes)
#POPUP= German Diplomatic Decision (this line is ignored in-game)
#MESSAGE= Foreign Minister %NJoachim von Ribbentrop %N%N Now that we have captured Algiers, our intelligence reports from Spain suggest that Franco may be willing to join the Tripartite Pact.%N%N Abwehr reports that it will cost a total of %B800 MPPs (200 MPPs for 4 turns), to help put Spain on a war footing, mainly to feed the starving population. Franco will also seize some French territory in North Africa in return for his assistance.%N%N Be warned that the USA will react negatively towards this, but gaining a new ally and the strategic importance of Spain's location will probably make this worthwhile.%N%N Shall we invite Franco to join the Axis?

#NOTES= Spain was struggling to recover from her civil war and so Franco was very reluctant to involve Spain directly in the war, though he did provide much assistance to the Axis short of doing so.%N%N Given Franco's reluctance, to obtain his help Germany would have had to provide him with territory in North Africa and much in the way of food supplies.%N%N As you have made the effort to capture Algiers, unless the military situation elsewhere limits your ability to pay the cost of Spanish war entry, it will be best to say %B(YES).
