Features of Version 4.2.7 - OPEN

Hi

In one of the forum it has been mentioned that the error "Too many parameters for command 'open ' is because of using the old version . Recently i have upgraded to winscp latest version . My version no is 4.2.7

Even when I run the OPEN command in command line it is throwing the same error . I need to use the private key along with open command

open master@123.125.247.236 -privatekey="F:\test\mykey.ppk"
open scp://master@123.125.247.23 -privatekey="F:\test\mykey.ppk"

Please let me know is this a problem with winscp or problem with my syntax . It is bit urgent ,please reply back

Thanks
Raghav

There's nothing wrong about your command. If you run winscp.com -? what version does it print out?
