--- Comment #13 from Dmitry Timoshkov dmitry@baikal.ru --- (In reply to x y z from comment #6)
it works with patch (SDR# is still connected to rtl_tcp)! but... after a few minutes is another error and crash
Looks like the patch really helped. The crash now is related to the following message in the log:
err:gdi:alloc_gdi_handle out of GDI object handles, expect a crash
Could you try installing gdiplus with winetricks and see if that helps?
