--- Comment #3 from Daniel Bermond danielbermond@yahoo.com --- (In reply to Michael Müller from comment #2)
The Wine Staging 2.8 release added more correct fake dlls, which gave MetaTrader 4 the possibility to enable some additional anti debugging checks, by comparing the content of the fake dll and the builtin ntdll. We were able to identify what the application is complaining about and will fix the regression till the 2.9 release.
Thank you for the reply and support.
