Multiple issues with Indesign since 17.2 update- lagging cursor, laggin text adjustments and more.

Hi, 

I posted on this the other day but I thought I'd update. Whether this is to do with the update or not I do not know - but it's happened since the update.

I use Indesign every day, and these issues have all appeared at once, they've never happened before. Let me summarise:

• Hovering over the layers / pages panels is like the cursor going through honey and flickering constantly.
• I've been unable to move the indesign window to another part of the screen unless I click in a specific place on the black bar at the top (most of the left hand side of the top bar)
• Selecting text and making adjustments like size or leading - it will only make the adjustment when you click away from the text or object, not while it is selected. So i have to click out of the box to see what the effect on my text not while it is seelcted.

Is this familair to anyone and is anyone able to help please?

Many thanks,
