I've done a function that estimates a mixture of gammas to fit some data that I have. This function is executed several time inside a cycle. If I run IDL with breakpoint (one for each cycle) it works but if I run it without breakpoints the program stalls (stop responding). I left it running during one day (much more time than it should need to execute) and my program didnt finished. I know that this is a bit strange.. but anyone got the same problem? Best regards,
