Re: Titelling image array in montage -- German umlauts

Thank you for this hint; I didn't know that.

I have just tested it and found that you may as well directly start a DOS shell window with the option "/V:on".

I however don't think that is is recommendable to rely on code which uses "!variable!", because there are other ways to invoke batch file processing, like Drag & Drop or SendTo. And these start the CMD shell without this option.

Or is there a way that ensures that a DOS shell is always started with the option "/V:on"?
