I don't know what time warp you just stepped out of which required you to
start responding to old messages but we're actually on Cygwin 1.7.13 now.
CTRL-C works as expected both in a console window and under mintty.
If there is actually still a problem which is not related to some
strange form of extreme jet lag then it would be nice if someone
recounted the exact steps to duplicate it. There is no need to offer
strange workarounds or hopeful thoughts. As always, we need details.
By details I mean a non-editorialized, adjective-lite series of commands
showing the problem.
What I did was type "bash" in a command window in Windows 7 64. Then I
typed CTRL-C. I also typed asdef^C and got a new prompt. I did the
same thing under mintty with the same result.
