I was just about to post on this same problem (with my 9400) but my issue is intermittent (which I find even stranger). I think it has to do with how we are calling executeActions() (I use "this.executeActions()"). The only reason I think its this is because I have some soft buttons with issues that I am not using onHold, I'm simply checking some things and running "this.executeActions()".

I've found what they've added but not what they've changed and from the PS docs (and I haven't found anything in the Proto Certified site either). Does anyone have this? or maybe know what JavaScript engine and version they are using?

I should also note, my XCF was created in PEP2 and updated to every release since
