Summary:	0007597: keyUp events reported incorrectly on SqueakVM
Description:	The standard VM reports keyUp events incorrectly if two keys are depressed. The keyUp event is reported for the most recently depressed key, not for the key that is actually being released. Works correctly on Cog, defect exists for standard VM on unix and Mac (not sure for Windows).
Steps To Reproduce:
Additional Information:	Reported on vm-dev list by Matthew Fulmer (HandMorph-handleEvent.st referenced in the mail posting is attached to this bug report): Date: Wed, 12 Jan 2011 20:30:47 -0500 From: Matthew Fulmer <tapplek@gmail.com> To: vm-dev@lists.squeakfoundation.org Subject: Re: [Vm-dev] Where are precompiled stack VMs or interpreter VMs?

File in the attached changeset. (don't show keystroke events) do: "HandMorph showEvents: true" quickly, press A, press B, release A, release B. you should see these flash by the top-left corner of the screen, and on Cog, this is what you see: [keyDown 'a'] [keyDown 'b'] [keyUp 'a'] [keyUp 'b'] on the official VMs, you instead see this: [keyDown 'a'] [keyDown 'b'] [keyUp 'b'] (you can of course use any two keyboard buttons) It's an issue on mac and linux at least.
