App only supports one window and doesn't respond to clicking on tree file or drag and drop once it has a file open

[rdmpage]

The app supports a single window view. If I have a tree open and I click on another tree file in finder, I get taken to the app, but nothing changes (whatever tree is currently displayed remains unchanged). Likewise, if I drag a tree file onto the icon in the dock, we switch to the app but the tree doesn't change. I guess I'd expect either:

• new window opens with new tree
• app asks if I want to replace current tree
  I'm not sure what the convention is with Electron or Tauri-based apps, are multiple windows a thing?

@rdmpage Yes - I have noticed some issues with the Tauri app on Mac with the standard Mac way of doing windows in an app. Will try to sort it out. @sav-che For Windows, I am less certain (and I don't have Windows for testing). My understanding (but this may be outdated) was that Windows opened a new instance of the App for each file.

@rambaut My bug report may be outdated as more recent versions do support multiple windows and do respond to drag and drop.

One thing I've noticed is that when the app boots up if there's an update it tells me what version i have and what new one is available. But if I've updated there doesn't seem to be a way to find the current version (e.g., in the "About PearTree" dialog). Hence I can't post a bug report saying "this happened in version xxx".
