Catalina: Finder not refreshing with new items.

So, I've seen this happen a few times now. Items saved from (primarily) Adobe products to locations on the disk, such as the Desktop or Documents folder, among others, do not appear as icons or in the finder windows until I relaunch the Finder (I'm using "killall Finder" in Terminal). They do show up in the Adobe file save/open dialogue boxes, though.

I'm not certain this is an Adobe-related issue, but those are the pieces of software I've been using.

I don't have a terribly congested desktop or file system, but it does interface with a couple network shares. I saw a Mojave-related thread from a little while back which suggested deleting the com.apple.finder PLIST, but that file's not present in any of my libraries.

Any help would be appreciated... Although periodically killing the Finder is somewhat satisfying, not knowing that it should be done until I notice a problem is, well, unsettling!

Other info: iMac 5K, 2017. 64GB RAM, various peripherals (2 external hard drives, network shares, OWC thunderbolt 3 dock, Dell secondary display using TB3/DisplayPort adapter).

Thanks! :D
