Hi fmanfredi76,
Ok, so in the cases where you still have problems when you don't change presets within 5 secs, would you be willing to give us some specific information.
1. What software version are you running (you should get the latest)
2. What preset(s) does this occur between?
3. Does it always predictably occur between these presets?
4. If they are your own custom presets, would you send us a dump or just tell us the settings?
Basically, we need to be able to duplicate the problem here on our end before we we can attempt to fix it.
Thanks
