[squeak-dev] Syntax Error window locks up image

Hi John-Reed,

can you tell us more about that method your are running every hour?

Syntax errors are as tricky as debuggers. They actually use a debugger internally to interrupt the current (i.e. the compiler's/parser's) control flow and offer interactive means to fix syntax to then continue compilation.

Considering interactive syntax correction, I am not sure whether compilation is safe in processes other than the UI process.

Did you try hitting [CMD]+[Dot] in that case?

Best,
Marcel

What causes a window like this to appear?
Why does it lock up the image?
The problem occurred in an image that was running unattended using #Delay to run a method every hour. The application is in development but it has been running on schedule for a month or so without any problems.

I do save and restart the image occasionally.
