@6bruno6, the collision boxes created in Spriter load correctly and can be used to detect collisions, but since the scml plugin will be moving them around and animating them, you usually won't want to put a behavior on them. So it's best to create a sprite called 'playerbox' or something like that. And then use the pin behavior to attach the scml object to it.
@MikeMS, That is a bug. It must have been introduced recently. Also, your condition says >=600ms, so if the bug wasn't present, it would try to play it pass this condition and pause itself again, so it would need a system condition Trigger Once While True under that condition. However, even if you fix this, it won't work because of the bug.
I'll be announcing a pre-release of the upcoming Spriter build tonight, and then I'll do an update to the c2 plugin for release over the weekend to fix the bugs that have been reported. After I complete the full release of the upcoming Spriter build, I'll add the remaining features to the plugin. Thanks again for you patience everyone. I'll post back here with the details of the pre-release later tonight as well.
