Expected Behavior

I want "Find" dialogue box to not to get closed untill I hit "escape" key or "close" button.

Actual Behavior

Find dialogue box closes by itself after "Find All in All Documents" & "Find All in Current Document" commands.

My Solution

I know that for programmers, the present scenario is ideal. But I use notepad++ for research purposes & it is one of the core application of my workflow.
I would be really happy if there was a checkbox under "Settings"--->"Preferences..."--->"MISC." for controlling "Find" dialogue box behaviour.
That will not upset the programmers either.
