Hi,

There is an annoying bug I've been running into on the 3.8-6665 image. It is totally reproducible from a stock image.

1. Open the image, elect not to do updates.
2. Open a workspace.
3. doIt: Smalltalk at: myForm put: nil
4. doIt: myForm _ Form extent: 100@100.
5. Open a Browser.
6. Middle-click in leftmost (class category) pane, search for

class Form. 7) Left-click on any category in the method category pane. 8) BOOM! MessageNotUnderstood: UndefinedObject>>beginsWith:

Seems to be something to do with _ to := conversion and the SystemDictionary. Maybe I'm doing something wrong that is making the system flake out, but I don't think so...?

Not a bug. You are putting nil as key into Smalltalk, which is simply a Bad Thing To Do. Stop doing that. Smalltalk keys must be *Symbols*. They should be uppercase, too:

Smalltalk at: #MyForm put: nil

To fix your image, do

Smalltalk removeKey: nil.

Avoid to use global variable. If you write code like Smalltalk at: mlkjljlk put: lkjjlj

there is something strange with your design.
