--- Comment #6 from David dav75uk@yahoo.co.uk --- Unfortunately not. The CBReader give-away doesn't suffer from the problem which suggests they changed the code sometime in between. ChessBase also are not sympathetic to wine as they are worried that they'd have to support their application on other platforms.
I'd be happy to jump on a zoom call if you wanted to take a look.
(note the issue of the scrollbar not being drawn on first display bug 47086 still exists so is unrelated to this fix)
