|0007597||[Squeak] VM||minor||always||01-13-11 02:22||01-13-11 03:16|
|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).|

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:
on the official VMs, you instead see this:
(you can of course use any two keyboard buttons)
It's an issue on mac and linux at least. Not sure about windows

the bug is present on the official linux VM
I think, but am not sure, it is present on the official mac VM
I don't know about the official window's VM
the bug is fixed on the Cog linux VM
the bug is fixed on the Cog windows VM
I don't know about the Cog mac VM
This bug is notably fixed on the old 3.8-era Croquet VMs (all platforms), which may explain why it is fixed on Cog
