This Program B does this general initialisation and then starts a timer which then fires of the rest of the startup code which is long running. Some of the long running code takes 20-40 seconds to run (calculations) and it doesn’t respond to minimising/maximising while that is happening which is another minor issue – I may need to put some extra processmessages calls in there eventually.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'>This relates to a previous question – the long running calculation sets up some quite large arrays and I tried saving/reading them in from disk to bypass the calculations but it produced a stack overflow. I am presuming that this is not from the code, as Russell’s code to save and load arrays to disk ran standalone, but due to the program using a larger amount of memory.
