I have only .NET 7.0 ( (Download .NET 7.0 (Linux, macOS, and Windows)) installed on all my systems. Is WWL 7.2.274 fully compatible with it? The reason I ask is that an odd problem has recently started occurring on Win11x64Pro systems. On a system boot, it takes several minutes before the italics mode successfully disappears. This is not occurring on my Win10x64Pro systems with .NET 7.0.
Weather Watcher does not use .NET 7, so that addition to your system would have no negative impact on Weather Watcher.
