[DUPE]Serious issue with FXPansion Geist in Cubase 8(.0.5)

[Mod Edit: Links to http://www.steinberg.net/forums/viewtopic.php?f=230&t=72994]

Hi,

There seems to be a major problem with Geist and Cubase 8.

I noticed since Cubase 8.0.5 Update, I am not able to open any dialog in Geist.
Neither the “menu” like Geist/About nor Save or else will work.
Also other Dropdown lists are not working (nothing happens when clicked) like Output assignment or any of the dropdown menus for FX.

Please help, totally ruined currently.
(Happens even when creating a fresh project; and disabling "always on top of the VST window will no help either)

Thanks
