I have successfully installed Toolkit and Piced under Wine on Ubuntu 13.04 (64-bit), however I have an issue that I hope someone can help with. Toolkit can see existing projects, but does not read the Network and associated structures. This happens with previously existing projects, and new projects created on the Ubuntu machine. Here, I have created a new project, added a network and a group in the Lighting application: [URL]https://docs.google.com/file/d/0B1biDb_qxVfQbDVEQmRKd3UxaDA/edit?usp=sharing[/URL] [URL]https://docs.google.com/file/d/0B1biDb_qxVfQWEQ4NmR5LVhqT3M/edit?usp=sharing[/URL] After closing and reopening Toolkit, I can no longer see the network: [URL]https://docs.google.com/file/d/0B1biDb_qxVfQVXNrTExRaUFMQm8/edit?usp=sharing[/URL] Here is the xml file, showing that the structure has been saved: [URL]https://docs.google.com/file/d/0B1biDb_qxVfQM1NHdHI5R0VYclE/edit?usp=sharing[/URL] Finally, if I use my Windows laptop it works perfectly: [URL]https://docs.google.com/file/d/0B1biDb_qxVfQTFQxLWczMlVZQ2s/edit?usp=sharing[/URL] This is my Java version: [URL]https://docs.google.com/file/d/0B1biDb_qxVfQYW1xZHdKWTV5UFU/edit?usp=sharing[/URL] Any help much appreciated! Thanks, Jonathon.
