This log unfortunately doesn't show anything. I hope you will find something similar in all these cases so I can try to reproduce this.@speedfire: I can confirm that FCC is becoming really polished with the latest test releases, but I also still get random hiccups once or twice per week.
I just had one of these situations again, i.e. FCC became unresponsive for about one or two minutes and then force closed. I took a LogCat log just after this happened and attached it to this post, so you can have a look what went wrong and hopefully fix it.
Thank you and good luck for finishing the current rework of FCC Launcher.
