access violation caused by multi-key down bug #615
Description
Exception class: EAccessViolation
Message: Access violation
To get more information, use the debug version.
repro steps:
hold U
hold LMB
drag mouse
hold M
release LMB
= access violation.
i suspect this is caused by lazpaint activating tools using key-down event rather than key-up, thus as long as a key is down (and can be seen in toolbar) lazpaint keeps switching tools.
a single key-down doesnt cause access violation, however due to lazpaint relying on key-down it keeps changing tools rapidly, e.g. U will cause lazpaint to switch between rect vs ellipse.
this behavior is also very noticeable on my 1000hz polling rate keyboard. (1ms delay)

not that im familiar with lazpaint internals, but this is a new installation of Widnows, i dont have lazarus installed to possibly debug it and know the whats going on.
