    For:

    • DRPython 3.11.3
    • Windows 7 64-bit, fully patched
    • Python 2.7.6
    • PythonWin 2.7.6

    If in the DrPython directory I double-click drpython.pyw I receive the following error messages:

    IDAT: invalid distance too far back
    Couldn't load a PNG image - file is corrupted or not enough memory.
    Failed to load image from file "D:/Python27/DrPython/bitmaps/16/unmodified.png".

    • The image file unmodified.png does exist in the cited directory.
    • If I paste the path name into Windows Explorer location bar, Windows Explorer recognizes the path and my default graphics editing program opens and displays the graphic without error.
    • Python otherwise appears to be working properly although there are many aspects of my 2.7.6 installation that I haven't exercised.

    I'm surprised that no one else appears to be having the same problem.

    Any ideas?

    Cheers & thanks,

  • That is strange. The wxpython Demo is running without problems?
