Find in: default status for lock to source folder?

Utility panel: Find in dialog

Whenever I open the dialog/panel with Ctrl+F the button "Lock to Lister Source Folser (Alt + L)" is enabled.
I would like for it to be disabled by default. Could not find out how to. How to?

If you make the button run Find in {sourcepath} (to open for the current path) or Find in "C:\Path\You\Always\Want" (to always open to a specific path) then it won't be locked, unless the path list is then reset.

ok, thx, but now I have another problem:
trying to close the find in-panel in a dopus running from a usb stick it takes almost 7 seconds for it to close. ideas?
