Pharo 7 image does not load

by sergio ruiz

I have been working in my image all day today, and it was working great. This evening, when I went to fire it up, it appears to start, but I am not seeing the image running. The icon hangs, and it does nothing. Here is an my debug.log for just one iteration of this. Any help would be appreciated! https://gist.github.com/sergio101/c86396d10f6fea4923b59930ad44a2a0 ---- peace, sergio photographer, journalist, visionary Public Key: http://bit.ly/29z9fG0 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
