Thanks for your response. I tried the previous Zero XV version: ZeroXV_unicontroller_2_5_0.exe but unfortunately that displayed the same issues. What I have been able to do in the meantime is to overwrite ver XV of UniController.exe with ver XIV and that seems to work just fine. I've got all the modules for ver XV running under the ver XIV controller. Not ideal as future module updates may well break this configuration, so I would like to see a proper resolution in the future. I suggest the simplest solution would be to just enable all the window controls so that it can be maximised and resized at will.
Something else that you might be interested in is this; My installation of ver XV running under the ver XIV controller is in a new folder at c:\wamp. There's something odd about the default installation of c:\UniServerZ. Having got a fully working version of the server and controller in c:\wamp I tried the same trick of copying ver XIV controller into my original installation at c:\UniServerZ. Rather surprisingly I got the same unusable minimised controller screen. The same controller that works just fine under c:\wamp does not in c:\UniServerZ. Also, installing any ver of XV into any folder doesn't change the overall issue for the XV controller screen. So this is the result of my findings.
ver XIV controller screen runs at normal size anywhere other than in c:\UniServerZ.
ver XV controller screen doesn't run at normal size anywhere it's installed, regardless of what the base folder name is called.
I'd be interested to see what you make of that.
