Wine DVM Performance Degraded?

I installed WineDVM to run and antique 16 bit program I still like to use about a year ago when I first moved to Win11 (new machine).

It worked well... with very slight delays for initial startup vs. when it last ran in native mode (Win 7). Otherwise it seemed like performance was fairly normal. As of a month or three ago, performance dropped. It appears directly related to interacting with files in the parent OS.

If I just start the program bare it comes right up. Full speed ahead. But if I run it the normal way for me i.e. opening it's data files as it starts - it's very slow. 30 seconds to load the trivially small config & data files. It used to take just a few seconds.

If I start bare and open a single data file, it's 25 seconds to open it. It used to be instantaneous.

If I choose Open > File after starting bare, the File dialog comes right up. I can pop through the directories at normal system speed. But even if I Cancel that Open box, it's 15 seconds before I can resume normal program operation. It's "hung" during that time.

File > Save is equally slow as Open.

All other program operations are normally fast. Printing is fast.

I have another 16 bit program that uses WineDVM. It still operates at normal speeds. It's a more trivial program, but it seems unchanged.

I haven't upgraded WineDVM yet (Installed April 2025). I don't see any updates to the 2023 release I installed in April 2025.

Thoughts? Some windows update that inhibited WineDVM?

FWIW, my problem as resolved itself in the last week. File operations through Vine are back to reasonable speed.

The only Windows changes I see in the time frame are:

I haven't done any other program installs or updates. It's possible it could be my A/V but I did try shutting that off at the time of my original post and it made no difference. Also, I don't think it has updated recently, but I am in the process of locating/checking log files to see if it's possible.
