Very interesting. Also exists lower levels which you can try:

         Valentina.DebugLevel  = EVDebugLevel.kLogErrors
    

Steve, I think its a Valentina bug. So please try send me your project ...
May be even compiled windows app...without VComponents
So when I will run it on my computer, your EXE will start to use my debug
dlls. You see?

Also interesting ... Or your test project still have SOME difference which
you do not see yet.

May be it is side effect of some RAM corruption...
Such bug are incredible hard.

So what about your EXE which do crash ?
