Is anyone using a recent Pharo with Windows 10? I'm using Pharo-7.0.0+rc1.build.44.sha.d3be1c018447fa5f7ba666cea7aff396f36d4309 (64 Bit) and am getting crashes whenever I try to commit anything using Iceberg. This seems to be a recent issue -- if I open an image from a few weeks ago, it works. Also, when I reopen the image, and the try to open the "Code Changes" it fails with: ------------------------ GrafPort(Object)>>error: GrafPort(BitBlt)>>copyBits GrafPort>>copyBits GrafPort>>image:at:sourceRect:rule: FormCanvas>>image:at:sourceRect:rule: FormCanvas(Canvas)>>drawImage:at:sourceRect: FormCanvas(Canvas)>>drawImage:at: HiRulerBuilder>>form HiRulerController>>buildRulerForm HiRulerController>>refreshRuler HiRulerController>>values: HiRulerController>>updateFromTree [ hiedraRulerController updateFromTree ] in EpLogNodeGraphPresenter>>initializeHiedraController in Block: [ hiedraRulerController updateFromTree ] BlockClosure>>cull: BlockClosure>>cull:cull: BlockClosure>>cull:cull:cull: BlockClosure>>cull:cull:cull:cull: [ :announcement :ann | aBlock cull: announcement newValue cull: announcement oldValue cull: announcement cull: ann ] in CollectionValueHolder(Model)>>whenChangedDo: in Block: [ :announcement :ann | ...

I've tried using the latest vm's from both files.pharo.org and bintray.com. John Brant
