Known problems in current version

  1. The layout of window elements might be impaired on high resolution displays such as MacBook?s Retina. The Ozone team plans to eliminate this shortcoming in the near future.
  2. The debugging experience might be impaired when debugging compiler-optimized program code. This is not a bug in the software but rather a result of information loss during the compilation phase. It is advised to recompile programs with optimizations turned off prior to debugging the program. See your compiler?s user manual for further information on how to disable code optimization.
