At the moment they always open centered over the window they're from.
If you want to move them because they're in the way, a good solution is to hide them entirely (initially) and use the Jobs Bar to monitor progress instead. The Jobs Bar buttons show the main progress details and can be clicked to see the full progress dialogs.
That can be done by turning on both of these:
-
Preferences / File Operations / Progress Indicators / Jobs Bar / Display the jobs bar automatically when starting a new job
-
Preferences / File Operations / Progress Indicators / Minimise progress indicators automatically
You can also have a button/hotkey which toggles the Minimise option, if you only want it sometimes, via the Set MINIMIZEPROGRESS=Toggle command. Full button definition with icon etc. that can be pasted to a toolbar or menu:
<?xml version="1.0"?>
<button backcol="none" display="both" label_pos="right" textcol="none">
<label>&Minimize Progress Dialogs</label>
<icon1>#statusbar</icon1>
<function type="normal">
<instruction>Set MINIMIZEPROGRESS=Toggle</instruction>
</function>
</button>
