I am using the respawn template "menuposition" and was happy with the fact it didn't pop-up at the beginning of the mission.
Now the intro is hidden by the menu and also the mission stops because the script that I use to check if the player switched sides is confused (respawning player is civilian with "side player" and west or east with "playerSide").
I tried the respawnOnStart = 0 parameter in the description.ext file but this parameter has been apparently removed or maybe it is not working.
We definitely need the respawnOnStart parameter. The respawn dialog is pretty much unusable like this.
I created a workaround fix until the situation is solved: http://forums.bistudio.com/showthread.php?176102-GLT-Respawn-Template-Fix
After reviewing GLTLegislator's addon I understood a more simple solution is possible and tested it.
The function responsible for this mess is BIS_fnc_initRespawn. So all you need to do is change it like this:
allowFunctionsRecompile = 1;
BIS_fnc_initRespawn = {true}
