And by incredibly, I mean that after the smallest edit you can see the screen re-draw and, for example, selecting an object in layout/design view takes several seconds or longer. When it fails to respond at all I don't get the standard windows message, but the top ribbon in Access flickers "not responding".



It's not a feature of my database - the same thing happens when I've downloaded elementary MS templates. It happens without any other programmes running on my PC (i7 CPU with 32GB RAM running Windows 10 64-bit, so not underpowered), but I don't have any problem with any other programmes. It's intermittent, in the sense that some days it works normally but most days not. The problem seems to be my installation of Access, but that comes from an Office 365 subscription, so I don't know any way of re-installing the programme. Any suggestions would be very welcome.
