Studio has suddenly stopped adding terms to my trusty termbase without giving me a notification. (Hence the many, many terms I thought I had added yesterday and today to my project don't exist :). "Add term" and " Quick add term" not greyed out in Studio, btw.

Also, termbase viewer window behaves erratically -- refuses to appear, or disappears after 10 seconds or so, or flashes (!) on and off. Most often "flags layout" or other layout options are greyed out, but even when I can occasionally select e.g. default layout, because I have docked/undocked a window etc. I still cannot add term.

Tried to resort to Multiterm proper instead, but no success at all. All that happens when I try to add a term is an empty tab labelled " [...]"

I have tried: resetting window layout, docking and undocking

I have tried: updating both Trados and Multiterm.

I have tried: creating a new termbase based on the old one

I have tried: using another termbase

I have tried: restarting Studio, restarting Windows, renaming folders under App Data/Roaming (both Trados and Multiterm), using Windows "repair program" options for both Trados and Multiterm.

At my wits' end -- I really need to get this sorted asap!

Any suggestions about what to try would be enormously appreciated!!!
