Summary: property sheets aren't modal Product: Wine Version: 0.9.37. Platform: PC OS/Version: other Status: NEW Severity: normal Priority: P2 Component: wine-misc AssignedTo: wine-bugs@winehq.org ReportedBy: thestig@google.com
Property sheets that should be modal aren't. So if a parent window creates a property sheet window, users can still interact with the parent window on Wine, whereas they cannot on Windows.
To illustrate this problem, I wrote a small test program. The test program immediately creates a property sheet window. On Wine, you can close the program by closing the parent window (with the white background) but you cannot on Windows.
