11.3 with Virtualbox 3.2.6 guest additions - how to check for install errors?

Hi, I’ve just installed 11.3 in a Virtualbox 3.2.6 VM and installed the 3.2.6 guest additions. Everything went as expected, with no apparent errors. However, when I restarted the VM I’m noticed I’m missing a number of options from the VM Machine menu, namely Seamless mode and Disable guest display Auto-resize, which seems to indicate something is not well. I also cannot resize SUSE desktop.

I have a number of VMs running an assortment of linux and windows and this is the first time I’ve encountered this.

So, is there a way I can check for errors. Is this a known problem or should I be asking this over on the Oracle forums?
