Some functional keys such as Enter, Tab, etc. works if only they are pressed twice

[Tarasov Alexey]

Hello!

I am using the latest version of Cygwin/X. I'm connecting to remote X 
client under FreeBSD with command X -query IP.ADRESS. When it connects, 
I must press functional keys twice to have any result. How can I get rid 
of this?

Best regards,
Alexey.
