--- Comment #2 from Forester pbronline-wine@yahoo.co.uk 2009-01-27 12:55:42 --- Yes this is still very much an issue with Wine 1.1.13.
I can confirm this issue also affects WordPerfect 10 and 13.
I have a work around. For WordPerfect version nn, delete the registry entry
HKEY_CURRENT_USER\Software\Corel\WordPerfect\nn\MDI Frame Position
This must be done each time the application is (to be) started.
I suppose the next step would be a simple test case that writes and reads back the offending registry entry. Which debug channel should I be tracing registry read and writes with ?
