Still trying v5.2. I have come across a couple of problems.
1st was the Cart Players. Now we have drag&drop option to drag contentment from player to playout list, clicking or tapping (I have touch screen) on the cart it does not always play first time, particually after changing tabs in the cart player from one set to another. Works on a second push. Turning the option off cures the problem. Not a great problem, but makes the feature a little un-useable.
2nd main players experiencing a similar problem. occasionally these wouldn’t play from mixer push button via VellmanK8055 or the screen. Again requiring a second push. This appeared to happen after using search or tabs in the right-hand window.
I have been unable to recreate the second problem after re-booting, but I haven’t had sufficient time to do further testing.
