The Working Title GNS530 is now part of the base sim.
It is an excellent product but unfortunately, it suffers from a small bug that blocks the interaction with the mouse for our GTN750 product. The hot GPS swapping code may also prevent some other html gauges to power on after a flight restart.
Working Title found a way to fix that but this requires some work from aircraft providers. Currently, only a few of them are compatible (ex Carenado PC12 and Ovation).
While waiting for this solution to be available in all involved aircraft, we are obliged to publish a package of the WT GNS530 which fixes the mouse interaction issue.
The code of WT remains absolutely identical and the behavior will be similar. We just fixed the interaction and the hot swapping issues.
When WT releases a new version of their GNS530, we will also release a new fix package if necessary. Please consider updating in this case.
We apologize to WT for releasing a patch. We have no other choice for users to enjoy our product as well.
