Thank you very much. Excellent work.

Try this patch and regenerate eventProcess. The performance will be much
better.

WxEvtHandler>>runEventProcess
    EventProcess ifNotNil: [ self stopEventProcess ].
    EventProcess :=
    [
        [ true ] whileTrue: [
            (Delay forMilliseconds: 5) wait.
            100 timesRepeat: [Wx processEvents].
        ].
    ] forkAt: Processor
