Layout issues of "Not Found:" dialog in lister

[now]

The "Not Found:" dialog that pops up when a search fails should have an icon. I don't know which one. Notepad uses information, iexplore uses error. Also, I think the "Not Found:" message should go in the dialog and not the title. Otherwise it isn't immediately clear what's going on.

And for next release, perhaps the message should be "Text not found: %s" and the title could be "Search Failed" or something like that.

No biggie, just a possible future enhancement.

Thanks!
