Scratch appears to be generating Smalltalk errors
Fresh install of Scratch 1.4 for Mac on a brand new Mac mini running OSX 10.8.3. When I start Scratch, I get the following error in a pink dialog box:
A primitive has failed:
UTF8 class(Object)>>error:
UTF8 class(Object)>>primitiveFailed
UTF8 class(Behavior)>>basicNew:
UTF8 class(Behavior)>>new:
UTF8(SequenceableCollection)>>copyFrom:to:
ScratchFrameMorph>>fixProjectTitleMorphLayout
ScratchFrameMorph>>fixLayout
ScratchFrameMorph>>updateProjectName
ScratchFrameMorph>>startup
ScratchFrameMorph>>saveImageForEndUser
I can dismiss it, but no motion Scratch blocks appear in the main window. Other blocks do appear. When I attempt to change the constant in one of them, a new error dialog appears:
Bad BitBlt arg (fraction?):
UTF8 class(Object)>>error:
UTF8 class(Object)>>primitiveFailed
UTF8 class(Behavior)>>basicNew:
UTF8 class(Behavior)>>new:
UTF8(SequenceableCollection)>>copyFrom:to:
ScratchFrameMorph>>fixProjectTitleMorphLayout
ScratchFrameMorph>>fixLayout
ScratchFrameMorph>>updateProjectName
ScratchFrameMorph>>startup
ScratchFrameMorph>>saveImageForEndUser
Any ideas?

It was a fresh install of 1.4 right off the main Scratch website. And I tried deleting it and downloading it again, with the same behavior. A system reboot also did not help.
Maybe it's just the operating system. Try downloading version 1.3 or 1.2 to your OS and see if that works.

Re: Scratch appears to be generating Smalltalk errors
No go. Scratch 1.3.1 throws exactly the same errors on this machine.
For what it's worth, I also have a Macbook Air running the same version of OSX, and Scratch runs just fine on it. This seems to be a problem restricted just to my Mac mini.

Yes, then it must be a problem with the Mac Mini. Although, I had a Mac Mini once, the only problem was that I couldn't share projects.
Out of curiosity, what action were you trying to perform?

Re: Scratch appears to be generating Smalltalk errors
It does this immediately when I start Scratch. It throws the first error before I even have a chance to attempt any action. The second error occurs when I try to change the value of any of the constants in a motion block.
This is a stock Mac mini. It is brand new (less than one month), and it does not have any other apparent problems. I have not done anything strange to the system configuration, except that I have MacPorts installed (but I can't figure out any way in which MacPorts should affect Scratch).
Any other idea of what I should try? I'd really like to get this running, as my son has expressed an interest in programming.

Re: Scratch appears to be generating Smalltalk errors
I'm not sure what else could be wrong. This is really strange.
Scratch has a way of disagreeing with Macs.
I'm sorry, but I can't figure out anything else that is wrong.
