====== Windows 7.1 SP1 - Listbox Check Redraw Problem ======


===== Environment =====

  * //Some// installations of Windows 7.1 SP1.
  * No other Windows release is affected.

===== Status =====

  * Resolved - custom checkbox solution released v1.0.96.

===== Description =====

  * On //some// installations of Windows v7.1 SP1 (minimum installation requirements for PergamonMU) a bug has been recorded across all software utilising the Xojo Development environment, and by a range of manufacturers. This bug results in the checkbox component of list boxes not redrawing with the correct true / false / indeterminate setting.\\ \\ While a visual problem only, it does result in users not knowing what the current settings of a value is and therefore inadvertently saving incorrect values.\\ \\ In some functional areas, this results in the software being effectively unusable due to consequence.

===== Actions =====

  * As Windows 7.1 SP1 is the minimum specification for Xojo software running on Windows and is also no longer supported by Microsoft, a 3rd party solution is unlikely.\\ \\ Esferico are currently developing a custom solution with our own checkbox images, not relying on the built-in controls within Windows.\\ \\
  * **UPDATE 2017-09-01** - Custom solution introduced with release v1.0.96.
