Research direction
Investigate the file save dialog implementation in Fyne, specifically under Windows. Look at the dialog package and any Windows specific code that handles file selection. The slowdown occurs only with administrative privileges, so focus on permission checks or file system enumeration differences. Check for known issues in the Go runtime or Fyne's Windows dialogs. No linked PRs or comments provide further clues.
