Summary: .REG files should be associated with Regedit Product: Wine Version: 1.2.2 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: christian.blackburn@yahoo.com

On any 32-bit copy of Windows .reg files are associated with regedit. Double-clicking on one will give you a yes/no confirmation dialog and if you hit yes that information will be imported into the registry file (providing the .reg isn't deleting keys vs. adding them).
The standard installation of Visual Basic 6's mouse wheel add-on will be broken until .reg files are associated with Regedit (providing one doesn't do a workaround like running regedit and then clicking on File --> Import). I've used a lot of other programs over the years that also required opening reg files, this might as well be the default behavior since it's the default behavior in Windows and it's just a registry setting.
To fix this bug, the attached reg file needs to be compared with other Windows XP users and then whatever is common, should become part of Wine. I'm not sure about the persistent handler (last 2 lines) values in my reg file.
