https://bugs.winehq.org/show_bug.cgi?id=54380 --- Comment #8 from TCH <tch(a)protonmail.com> --- I've started to rename the files in ~/.wine/drive_c/windows/system32/drivers/ and since you've said it is something with I/O, i started with netio.sys and after that DLPORTIO.sys which was the culprit. If that file does not exists, the debug window does not comes up. I've opened ~/.wine/drive_c/system.reg and searched for DLPORTIO and found the driver: "DriverLINX Port I/O Driver". That is a driver for windows to give access to the LPT port (and others) from programs. (http://pascal.hansotten.com/delphi/driverlynx-dlportio-and-windows-7-and-8-a...) However, that was working before i've upgraded to WINE 8. What's the problem now? I've tried to reinstall the driver, but to no avail. Evidently, removing the driver would cause the debug window to cease popping up, but why does this driver causes problems with WINE 8? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
