Hi bruce mccullar,
Since the game is already running but keeps switching between screen sizes, the issue may be related to how the game handles display scaling on newer versions of Windows. Older games such as Zuma can sometimes behave unexpectedly when high-DPI scaling is enabled.
You can try these additional steps:
- Right-click the Zuma shortcut and select Properties.
- Open the Compatibility tab and select Change high DPI settings.
- Check Override high DPI scaling behavior and choose Application.
- Click Apply and launch the game again.
If the behavior continues, please try the setting from the Independent Advisor before starting the game, then restore your preferred resolution after exiting.
Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
