[SOLVED] Program doesn't really exit after unload process

Hi,
I'm using in my application "CSocketPlus" (Winsock replacement) and "NotifyIcon" (tray) modules, and in Unload sub I properly unload Socket and remove icon from tray before "End" command, but problem is that program stays in memory until I launch Task Manager :confused: I tried many suggestions that I found, but none of them solves this problem :(
So, does anyone from here know solution? Thanks in advance!
