Query re loading HW Info


I don't know if I have mentioned it before but just lately I have noticed that when I open HW Info and then minimise it for any reason the program shuts down completely. 
Is there a way to keep it running because once that happens I usually have to reboot my machines to get HW to open again - pretty frustrating.
Is it possible that it minimizes into the tray, that might be hidden there ? Have a look at the tray icons, HWiNFO might be hidden there ^.
