Am I on track now?

You sure are. And, as an unsolicited tip, when you're popping windows in perlTk, try to use the same windows over and over, hiding and restoring windows as needed, changing names and labels as needed. I've found that perlTk program footprints in memory will grow as you Create new windows, which becomes a problem if the program runs too long.

Maybe one of the other monks knows a good way to address this problem. delete() and undef() haven't cut it for me.

Enjoy!

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
