--- Comment #8 from Ansgar muell@anse.de --- User PaulBGD compiled a few Wine versions and found that this commit causes the backspace issue in HeidiSQL, since release 4.9: https://github.com/wine-mirror/wine/commit/4a6e69ad3aff6fff2817b05ee2cdcc7e9... . Neither he nor me knows *why* this is causing it, so could anyone look into the few changes of that commit to find a solution?
