I just did an update of Cygwin on a Windows 7 box. When I open ConEmu to a Cygwin Bash terminal, everything seems fine. However, if I run GNU Screen, the terminal locks up until I forcibly kill screen.exe using a Task Manager. This was not happening before the update.
I tried other updates with other mirrors but it doesn't seem to help. I tried removing my .screenrc file, it also didn't help. I tried downgrading my version Screen to 4.3.1-1 and it didn't help either. I tried the newest version of ComEmu and it didn't help. I tried running Screen from MinTTY and it works okay (but MinTTY has some other problems with Screen so it's not a good solution for me).
I had another Window 7 machine and it also broke as soon as I updated Cygwin. It must be some sort of new version of some sub-library that causes this issue. Anyone have this same issue? Any ideas on how to fix it?
