There's an issue in CEF4Delphi that causes the ToolBoxBorwser2 demo to crash when the user clicks on the "Open" button to create the child window.

This demo works correctly in 64 bits.

It seems to be an incorrect declaration in CEF4Delphi of some of the new "Views Framework" components that only affects 32 bits applications.

The crash occurs right before the TCEFViewComponent.OnGetPreferredSize event because it tries to cast an incorrect pointer as a TCefViewDelegateOwn.

CEF4Delphi/source/uCEFViewDelegate.pas

Line 195 in 318318c

if (TempObject <> nil) and (TempObject is TCefViewDelegateOwn) then

This stackoverflow case might be relevant to this issue because returning a TCefSize record in TCefViewDelegate.get_preferred_size seems to be causing this issue.
