I'm using spyder 3.3.6
and, since a week ago or so, the debugger has suddenly start ignoring any breakpoints I define by placing a red dot with a double click on the corresponding line. Once I start debugging pressing Ctrl+5 the debugger stops at the first line of the code, even if there isn't a breakpoint. Then when I press Ctrl+12 to move to the next breakpoints the debugger just ignores them and terminates the process without showing any error message.
Have a look at the screenshot to get a better idea of the problem:
Any suggestion to fix this? Thanks.
