Yes, I'm sure. The sequence of my actions was as follows:
1. I launched Stencyl, cleared logs
2. Then I opened demo project (Demo- Miner), opened scene SimpleVersion
3. Next I opened Events tab, opened Attributes tab
4. Then click Add attribute button
5. After I opened dialog "Create An Attribute..." which contain list of attribute types, but types didn't have any names. If I click on the list item then typename appears as Type value in dialog, but the list item have empty name.
6. Finally, I clicked main menu\Debug\Logs\Generate Logs and saved log.
Did you watch the video which I uploaded to files.mail.ru?
Are there any tools which I can use for gathering more detailed debug information?
