Hi,
First of all that message is out of my control. I present it alright but I only detect that the OS has changed the resolution.
Then, what I notice myself is that this change by the OS tends to be there before any "real playback" has happened. So, install a new version (or new OS ?) and the message will be there until you played once in Unattended (or Minimized ?). Then after a while suddenly it never pops up agaiin.
One thing (which I think is important for Windows 8 ) :
The setting of 15ms results in this message by standard because the timing in W8 has changed, and instead of setting it to 15ms you should set it to "Max for this system".
That said, I have set it to 15ms (well, that's what I see for weeks in my system) and I also don't receive the message. But you can bet it helps to set it to max (and receive 15ms).
But you are on W7 ...
The system plays about 3 songs and then engine 3 stops.
You seem to put this in the context of the Clock Resolution, but I don't see a relation. It could though, because -as explained- receiving the message is rare anyway so I might not have the experience. So, *is* this related to the message you think ?
Otherwise be sure to be activated and that this is not about the demo play time being expired.
Btw, what do you mean "engine 3 stops" ??
If you have more insight for me, don't hold back ...
