Describe the bug
If i generate an highmap, and click open to get the save promt, even if i click on "yes", it does not show the file selection so save it.
Instead it just shows the open dialog to override the current map.
I think this happens if i already opened a highmap once, and then modify it by reprobing and then try to save it again.
Also, why not just add an dedicated "save" button ?
To click "open" to save something is as counter intuitive as it can possibly be.

To Reproduce
Should be clear from above ...
Although it does not always happen, but if it does, im not able to save a high map until i restart the programm.

I think the simplest solution would be to just add an save button to the high map menu.
One that ALWAYS opens the save promt.
