"I do know that even as a non-disabled user, the behavior Peter describes as "per spec" (that is, mouse buttons are not keys for the purposes of releasing the sticky keys) is counter-intuitive since the modifier keys interact with mouse buttons the same way they do with non-modifier keys (ie. Control modifies selection with mouse clicks the same way it modifies selection with the keyboard). Given that normal interaction with both non-modifier keys and mouse buttons, I'd expect instructions about how modifier keys behave to also apply analogously when both non-modifier keys and mouse buttons (but not mouse movements) are involved. Either that or I would expect modifier keys to not interact with mouse clicks the same way they do with regular keys."
In case you didn't know, this bug has hit slashdot.
The only useful comment there, though, seems to be this one: http:// linux.slashdot. org/comments. pl?sid= 4959535& cid=46607985 (which seems to reply to comment#5, so I'll quote it:
