Quick followup about hiding console window:

I found a small utility called ConsoleTool that served me a better soloution than running the script with wperl.exe - because when my script was run this way, the console (dos box) kept comming up every time the script needed to run some dos-batch files.
Instead I started the script in normal console window (with perl.exe) and from within the script called ConsoleTool. The script goes away (from screen/taskbar) and stays away even when dos-system-commands/batch-files are executed from within my script.

Nice.
