There seem to be people who agree that making all other displays just black is not a useful feature.

Re: [Pharo-project] VM freezes sending #basicNew to Stream subclass
I agree with you. Nevertheless it seems that there is a bug in the debugger. In a workspace, type this and debug it: Stream basicNew printString. Step over basicNBew. Step into printString. Step into printStringLimitedTo: 5 Step into streamContents: [:s | self printOn: s] limitedTo: limit Step over 100 min: sizeLimit Step over self new: (100 min: sizeLimit) -- error: the debugger tries to execute (String new: String) I also note that all class methods in stack window left column are miss-printed - like 'Block in class)'new: Stef On Dec 4, 2011, at 12:07 AM, Igor Stasenko wrote: On 3 December 2011 01:30, Stéphane Ducasse stephane.duca...@inria.fr wrote: We will have to track when this error was introduced may be this is the runtimeError fix that we pushed.

I don't think that would work with OB that has its own keymapping. The problem you observe is a long standing bug: if you don't have a text selection key presses are handled by Pharo not by OB.

Re: [Pharo-project] startup errors
+1 on the option being too late. Given my dislike of silent failures, I can't object to some means of drawing attention to the problem, and failure to start certainly does that. However, there should be a way to allow the image to start in the (likely?) event that it can assist in its repair or replacement.
