installer never completes if left running while screen times out

I've tested a few times by installing and uninstalling using the new all in one installer.

If the install process is left on and the screen times out, the installer never finishes installing and stalls at 98-99% for the last three items (namely CDK, JDK and JBDS).

Not sure if this is a problem specific to this device because I've only tested on this bug logging issue just in case.
