Everything got worse from simple stuff like:
Using the built-in ESXi webserver. If I right click a VM and then left click any option that has sub-options - the menu exits.
Using a shared drive? Well my Ubuntu VM won't boot. Haven't done anything other than install updates and reboot. I don't even have to mount the shared storage volume. Three times now. Feels bad. (No issues if I update/reboot without the shared drive attached).
There's a million other problems too, like random exceptions specifically in the ESXi web server (exception finding method ".toString()") Or my favorite, the blank exception error box using the ESXi in-screen pop-up with "details" and "ok" buttons (but details doesn't show anything).
The only explanation is if they off-shored research and development. Well, it was nice before they transitioned. I really hope they improve the quality of their software.
