Arrow keys don't work when used with Synergy

[wwinfrey]

I'm using SecureCRT 6.7.0 b123, on OS 10.6.7.

I'm controlling the keyboard and mouse on my Macbook Pro remotely via use of the "virtual KVM" software, synergy: http://code.google.com/p/synergy-plus/

When I up or down arrow, I expect to cycle through my shell history; instead nothing happens. I've tested with Terminal.app and iTerm2.app and neither of these programs exhibit this behavior (neither did older versions of SecureCRT...)
