What I can see from your post, is that you're having problems controlling the Slingbox using the keyboard.
In this case, besides doing a hard reset of the Slingbox, you can uninstall the plug-in and download it back, also, try from a different web browser.
If still the same, try running the Setup under a different model, if the problem is still the same, you can post the results here.
I've tried this on many combinations. I just installed all the plugins and stuff in IE, and connected it to two slingboxes. It does the same thing. Keyboard keys like down-arrow/up-arrow are NOT handled by the slingbox.com plugin. Another thing I tried just now that's revealing is I got rid of the remote, and just typed up/down-arrow with just the browser showing. I clicked on the TV image, hoping that would ensure focus for the plugin. When I typed up/down arrow, it just scrolled the browser window (I was on a laptop with a small screen, so the slingbox.com plugin content didn't completely fit in the browser window). Anyhow, that shows the plugin is not even taking the keyboard input -- the keyboard events are just going straight to the browser, which thinks you're typing up/down arrow just to scroll the window, not knowing you're trying to change the channel through the slingbox plugin.
