When launching C:\cygwin\bin\mintty.exe -i /Cygwin-Terminal.ico - (from the start menu) And while in the terminal I hit Ctrl-Tab, the window becomes dialog modal. Any ideas on how to prevent this behavior? $ mintty.exe -V mintty 2.7.7 (x86_64-pc-cygwin) C 2013/2017 Andy Koppe / Thomas Wolff License GPLv3+: GNU GPL version 3 or later There is no warranty, to the extent permitted by law. $ uname -a CYGWIN_NT-10.0 blackfat 2.8.0(0.309/5/3) 2017-04-01 20:47 x86_64 Cygwin -Jason
