Just got my watch and am going through the setup from a Mac (OS X 10.6.)
Running some different sample apps, I continually get this yellow box that renders down the screen on the left side. Top to bottom. It will overwrite any text that happens to be there.

What's going on?

Any help would be appreciated

That would be the falling box demo app which is the default app in the SDK.

Okay, but it is still present when another example is loaded. Example the prints button up/down. The yellow box just keeps rendering over everything. Is there a make clean or something that is needed? I am just following the get started guide.

Thanks

It sounds like the other app wasn't loaded properly. Try copying the source code into the /src directory, compiling it by running python compiledandload.py -c and then transferring it. If you are using SDK version 1.1.1 running compileandload -d wont compile the app before transfer, so it seems like it was just transferring the last compiled app which was the falling box demo. If you download the new SDK (version 1.1.2) compileandload -d will compile before transferring.
