Drag and drop in Tree stops working

[MAT_Blue]

I've had this problem for a while and I have it on every setup where I have FreeCommander installed. Drag and drop in the tree stops working. I get a red "Do Not Enter" sign when I drag something somewhere else. I've found that if I go into Tools->Settings->File/folder operations dialog and just hit "OK", it re-enables it. So somehow, it's losing the memory of those settings (I'm guessing) and going into the dialog makes it "remember". I have this problem every couple of days, it seems.
I've had the same problem on many subsequent releases. I'm currently on the 64-bit version of 949 on Windows 11 Pro 25H2.
