[Laszlo-dev] dependence on ExternalInterface in swf9

[Henry Minsky]

Oh foo, the "eval" feature of the debugger seems to be broken,I get this
runtime error whenever I enter an expression to be eval'd

Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an
unknown type.


I better see what it is trying to compile for these expressions.  Maybe
something

changed in the framework that broke the little "debug application" that gets

compiled for each eval statement.
