Just in case you are interested, the following exceptions appeared for the first time after updating to v4.0.3.34

Thank you Bernd.
I know about FirstChanceException. You had told me in past.
But following that, was another exception. That's why I sent you the log.
I though it might be helpful to you.

I assume you have this info out of the debug log file.
These are internal messages and only indicate a so called 'FirstChanceException' - however, they are all gracefully handled and do not represent any real error or exception.

I assume you did not see any real errors, issues or misbehavior.
Note, that the Debug Log info contains a lot of info, which is basically only valuable for me to see exactly what conditions in the code have been executed and which not - you need to be a developer and have the source code to really understand their meaning.

And as said, a 'FirstChanceException' only indicates, that there might be a first chance of an exception, but that ProppFrexx might handle this gracefully as as expected or that the exception actually must not necessarily happen at all- like in this case I assume ;-)

Oh, that exception is just the detailed output of the possible exception itself ;-)
I gather all info within my debug log file. The message "CheckForNextTrackToSchedule1 error" simply contains that info again; in that very specific case, the error message is simply repeated twice.
So nothing to worry about as well...
