Not sure why but I get an error after the mice have made a few turns. (Running on Windows 2000. The maze draws and the mouse start out OK)

An error box pops up too, the good old 'an instrution at blah blah referenced memory at 0x000000000. the memory could not be written', Click OK to terminate (I have to click this box four times (same addresses each time) beore it clears.

My Logo looks OK, at least the spiral and random box programs run fine. Any suggestions ?

Cheers,
R.

• 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).
• Want more info? How to link or How to display code and escape characters are good places to start.
