Hi! Currently on Windows RAW conversions open the unprocessed_raw.exe with flag SW_SHOWMINIMIZED which causes it to steal keyboard focus from active window. So it's pretty much impossible to do something else while the files are converting. Would you consider changing that to SW_SHOWMINNOACTIVE which opens the window the same way minimized but does not steal focus? Briefly tested on my system (Win 10) and seemed to work nicely.
