Many thanks for all your replies guys, I haven't had much time to check the thread as I don't have internet at home at the moment.
>> Andrea,
Thanks for your suggestions, I may make the program language compatible when I get a minute or two
I was thinking of including an increment for the prefix/suffix, but didn't get around to it in the end - but I like you idea of the Tab Search, that may come in useful
Oh, and thanks for the icon
>> Bjorn,
You are correct in that the tile mnemonics mean that you can operate the program using the relevant keys (the underlined letters on the buttons), but this of course will only work when the focus is on the main dialog, and not on the list_box. I didn't really want to clutter the dialog with more and more buttons, and so didn't want to include a specific help button...
Thanks for the comments guys, I'm glad you are enjoying the program.
Cheers,
Lee
