C5 Mixer channel selection slow

Running Cubase 5.0.0, when I click on a mixer channel the last channel selected stays highlighted along with the new selection , then after a second or two it switches to just the new channel selection. No problem in the project page. Thanks in advance for any suggestions.

Have also noticed that the display freezes until Cubase activates the selected channel . On closer testing the edit (project) page is doing the same. Audio playback is not affected.

I found about 12 instances of various J L Cooper remotes installed in ‘device set up’ .

Removed them and the channel select lag disappeared along with the graphics hangs.

This is a clean C5 install, I know that I didn’t initiate the J L Cooper remotes in the set up dialog… could it have been a glitch?
