111	Stop using Open32 registry in QSettings	Dmitry A. Kuminov		"It has shown that the Windows registry implementation in the Open32 Reg* API that we use for the QSettings storage has one severe bug: under certain conditions (I suspect an application crash while a handle to a registry path is open) it corrupts the registry database so that any further attempt to write to that path or to just delete it returns Error 87 (invalid function). Even worse, this problem is persistent -- after rebooting OS/2, the database is still broken and gives the same error.

The only way to fix the broken database I know of is to restore C:\OS2\SYSTEM\SYSTEM.DAT and C:\OS2\SYSTEM\USER.DAT from the backup. It's obvious that the backup isn't always available which makes the further use of Qt applications on the broken OS/2 system impossible. This situation must be avoided."	defect	closed	blocker	Qt GA	QtCore	4.5.1 Beta 5	highest	fixed
