Can't use Start8 with VirtualBox

First, Start8 is great.  Exactly what I am looking to use with Windows 8.

My problem is that I am not able to start VMs that have a lot of RAM with Start8.  I believe Start8 is reserving memory in a way that prevents windows from allocating a large continuous block to another process.  This is particularly noticeable when hosting a virtual machine.  I have 8gb of RAM with about 6.5Gb free after boot.  If I try to start a virtual machine with more than 3gb of RAM in Virtualbox I get an error "HostMemoryLow" and the VM will not start.  If I kill the Start8 program and the Start8 service it will launch as expected.  Strangely enough, killing those processes seems to have no impact on Start8 as it appears to work normally.  Also, restarting those processes seems to do nothing and allows the VM to load with more than 3gb of RAM.

I believe the problem is similar to a problem reported here:

This problem was with the way Google Chrome reserved memory and would prevent large VMs from loading.  I have not tested with anything except VirtualBox, but I would not be surprised if this error occurred with other VM tools as well.
