Hi, Iâm doing some travelling and had a stretch on a plane with Pharo 7 - 64bit b166, and was trying out some changes to Calypso to plug in some potential keyboard extensions. Anyway, in figuring stuff out I noticed the debugger had a number of issues - which I can try to investigate more but wanted to say something before ploughing on. When I hit a method invoked from the keyboard which has self halt (not a soft breakpoint, as I was changing code and didnât want to keep losing the breakpoint) - when I made a change and hit save I get an extra empty predebug window ? The older debug window also has a my single method but no stack and is not debuggable. The upshot is that I have to start debugging all over again? I also noticed that when I hit an error and got a debugger and then fixed the error, resumed but then hit another - the title of the window was still the old error msg and not the new one (so quite confusing). Has there been recent work done in the debugger that might explain these? Tim Sent from my iPhone
