Here's a fix:<br>

Hi,<br>
Image lock up doing<br>
Preferences togglePreference: #justATest<br>
<br>
If I change error: to inform: in the method I do not get a image lock up.<br>
<br>
This is in a trunk image and tested with several Cog VM on Windows.<br>

Preferences>>togglePreference: prefSymbol<br>
"Toggle the given preference. prefSymbol must be of a boolean preference"<br>
(self preferenceAt: prefSymbol ifAbsent: [self error: 'unknown preference: ', prefSymbol]) togglePreferenceValue <br>
