After running a shell script, the git bash console doesn't work anymore. Every time I press a key, it returns:

> 
> 29424339 [sig] bash 1962! sigpacket::process: Suppressing signal 21 to win32 process (pid 18320)
> 
>

`Ctrl+C` and `Ctrl+Z` don't fix the issue. The current workaround is to close and reopen the git bash. Is there a better way? (Unfortunately, I cannot post the content of the shell script here)
