[Vm-dev] StackInterpreter "simulation image" and options

That is good news, thank you.
I will see what I can do with it. First, I need to familiarize myself with the Simulator startup process and then I will look at that var/event mechanism.
Hopefully I can get that going and then move on to fixing some plugins.

I am hosting (? correct term) the StackInterpreterSimulator on Squeak4.5-13352.image running Cog.
I instruct the simulator to use a copy of that image that I have renamed to Squeak4.5.image.

vm := StackInterpreterSimulator newWithOptions: #().
vm openOn: 'home/tty/usr/src/smalltalk/buildCogDevelopmentImageCog.app/Contents/Resources/Squeak4.5.image'.
The simulation runs, but the simulated World does not respond to mouse clicks (the control panel of the Simulator works just fine).
Right. I've not looked at this. It never worked for me and I think its to do with the "new" event mechanism bssed around the interruptPending inst var. So for now I use an image that has a read-eval-print-loop in it. Much better would be for the input scheme to work. But I've not had time or occasion to look at the Interpreter and update StackInterpreterSimulator appropriately so it responds to input.
I would like to rule out a missing option in the newWithOptions: #() line
Specifically the "type of VM options in VMBasicConstants:
1. To my way of thinking, since I am running a StackInterpreterSimulator, passing the option #STACKVM makes no sense.
2. Also--if I remember correctly--when first running Cog on a StackVM (?) image, it prompts the user that running Cog will make the image unusable for the StackInterpreter.
3. Therefore telling the StackIntepreterSimulator to expect a COGVM image makes no sense either.
4. Equally perplexing is the fact that the simulation does run -- it is just stuck in idle--which tells me I am incorrect about 2. above.
I will be poking around in the guts of things in the mean time.
