appshot vignette example not working

[markriseley]

I can't make appshot work on my windows PC. I just installed phantomjs and have successfully run the first couple of webshot examples on the rstudio homepage. Here's console output from when I try the appshot() vignette example (which I ran after clearing workspace and restarting R):

> appdir <- system.file("examples", "01_hello", package="shiny")
> appshot(appdir, "01_hello.png")
Warning PhantomJS v2.0 not yet released. There will not be any official support for any bugs until stable version is released!
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
cannot open file 'C:\Users\Mark\AppData\Local\Temp\RtmpeI2i8Z\pid207878a65777': No such file or directory

However I do have this (empty) file in the same temp directory:
'file207878583cc9'.

I have tweaked several things on Windows and it will be great if you can test the current version. At least this example works for me on Windows now.
