If, and only if, the address is of the form:
\\someServer\someShare\someSubFolder
and I then
- Double click on the free area in the list (in order to move up), or
- Use history backward/forward
After clicking on OK of that dialogue, XY goes to the intended target location without any problem!
Interestingly enough (!!), this error dialogue does NOT appear on:
- Click on any of these locations in tree,
- Click on any directory in the list (i.e. going to a subdirectory)
- Click on any item in breadcrumbs.
