I have a dual-monitor setup running CLion under LinuxMint 18.
Lately I've noticed that when I do a Ctrl-Alt-F search for something, the resulting "Find in Path" window can be moved around on the monitor it happens to pop up on (often not the one the CLion instance is visible on), but cannot be moved to the other screen.
This becomes very inconvenient when I want to visually compare the results to information in a different window. I can move all other windows around across both monitors just fine, for example, another instance of CLion for a different project (just not _it's_ "Find in Path" window; it's locked to the single monitor _IT_ came up on).
XX Not sure if it's related, but the pin button doesn't seem to do anything but change the pin button's background from light to dark. Edit: Figured out that the pin button keeps the Find window from closing when you navigate to one of the matches.
