Selected puzzle 1152. Default track is set with Electron Density displayed along with puzzle bands, cuts, and freezes. The first and only action done is pressing "Wiggle Backbone" once and foldit crashes. Restarted foldit and it has now happened four time in a row. The Visual Studio error message is:
Unhandled exception at 0x76204598 in Foldit.exe: Microsoft C++ exception: utility::excn::EXCN_Msg_Exception at memory location 0x1578E900.
