<p>Thank you, but I already solved the problem and learned everything you said before I send the mail. I simply solved the problem by fixing the font. It seems that the mail was in queue and was sent after I solved it.</p>

&<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">There appears to be a corruption in Squeak's font structure for<br>
special-characters.<br>
<br>
The #fallbackFont of the StrikeFont refers back to the original<br>
StrikeFont, leading to endless recursion and locking up your image.<br>
This script identifies the fonts with wrong pointers:<br>
<br>
StrikeFont allInstances select: [ : e | (e fallbackFont respondsTo:<br>
#baseFont) and: [ e fallbackFont baseFont == e ] ]<br>
<br>
StrikeFont>>#widthOf: aCharacter -- if the aCharacter is a special<br>
character it will ask the #fallbackFont for widthOf: aCharacter, which<br>
turns around and asks it's #baseFont, which happens to be the original<br>
StrikeFont.<br>
<br>
The problem occurs when the fallbackFont is not already set. So this<br>
appears to be a bug with StrikeFont>>#fallbackFont.<br>
<br>
Do any of the font experts know a proper fix?<br>
<br>
