Thank you, thank you, Thank you! You gave me the key without even
realizing it. I had just wanted to give a running version to someone who
was visiting and had quickly tried to compile a release version. I stupidly
assumed the release version would keep the same project settings except for
the debug stuff. Turns out that Garbage Collection was not even enabled in
the release settings. As usual, I was looking in all the wrong places and
missed the obvious. Now it runs. Thanks again.
