I don't recall if this was reported...
I got the "exception" freeze (I am on os v 1.02) when loading samples into my project.
The freeze occurred when choosing the "select all" option to select all the files in a folder followed by the "load into project" command.
After rebooting the DT, I then manually selected all the files in the folder and loaded them into the project without problems.
Either the "select all"/load creates problems or...
After I had used Transfer to move sample folders into the DT, I went back and noticed that there was a ".DS_store" item in the sample folder. I don't know what the Transfer program does with that, but perhaps it gets sent along with all the samples, doesn't appear on the transferred files list, and creates some problem when the load to project is invoked.
I will be double checking my folders from now on the make sure that item is not present...
