@kalleboo@bitbang.social - I got those screenshots you asked for about the Type 1 crash. I have WindowShade capability installed on this System 7 Mac. With the FatBits canvas open, if I double-click the window title bar to collapse the canvas, then double-clicking to expand the canvas will cause the crash. This is occurring 100% of the time. Notably, it does not happen if FatBits window is closed, or if I press the dedicated WindowShade button. Only double-clicking seems to trigger it.

@theirongiant@hachyderm.io Thanks! Really strange crash, getting the status shouldn’t fail unless the window has been closed…

@theirongiant@hachyderm.io @kalleboo@bitbang.social Based on that screenshot, it looks like the crash occurs because something in CanvasWGetState attempts to access a field of the canvas window, and is dereferencing a nil handle. Doesn't WindowShade work by setting the visRgn to nil or something along those lines? What status is it accessing?
