No, there was no resolution. Problem still persists and is follows into vSphere 6.0.
Best way to get around this is to do the build from the thick client then install the tools. Theoretically after that, the console mouse should be stable.
This is pretty lame that we have to keep finding workarounds because their new version is crappy. They're going to phase out the thick client in favor of the web client but so far the web clients sucks in many aspects.
I'm currently testing Hyper-V for some of the less important VM's and so far so good.
The learning curve for new VM admins on Hyper-V seems to be faster as well.
Thanks
