I can no longer see write progress from Taskbar button???

When burning a ROM to cartridge, the green progress bar is no longer seen on the taskbar. So you literally have to check on the app to see the progress now. :/

Unfortunately it's not a FlashGBX bug, Qt 6 doesn't support yet showing the progress on the taskbar: https://bugreports.qt.io/browse/QTBUG-94008
You need the Qt 5 release of FlashGBX (using PySide2 rather than PySide6) to have the taskbar progress back.
