Add this line to the top of your PerlTray application: 
    Win32::SetChildShowWindow(0) if defined &Win32::SetChildShowWindow
+;

[download]
It should hide all applications started by system() if your version of Perl includes Win32::SetChildShowWindow(). It definitely is included in ActivePerl build 633 and later.
