<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'm using squeak 3.7a-5816 on windows and unix. I
ran into an infinite loop bug with some network/graph code and my image "froze"
and was using up all the cpu cycles.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This web page, <A
href="http://minnow.cc.gatech.edu/squeak/899">http://minnow.cc.gatech.edu/squeak/899</A> ,
describes the Squeak Interrupt key to stop run away squeak images. <A
href="http://minnow.cc.gatech.edu/squeak/2168">http://minnow.cc.gatech.edu/squeak/2168</A> is
also helpful.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>When the image is idle pressing "alt-dot"
brings up a debugger on a "user interrupt" exception. So obviously my image is
properly handling these "alt-dot" commands some of the time (and likely all the
time).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>As a test case I tried the following do
it:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>[true] whileTrue: [].</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The image dutifully exectued this and became
unresponsive to any attempts to interrupt it with "alt-dot".</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Can anyone explain what is going on? Why can't I
interrupt run away loops? Is there anything that I can do to ensure that I can
get in there and debug or stop these loops?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Cheers,</FONT></DIV>
