The problem only in error message, because save operation works properly.
In the example above I used the same file for both left and right panels (to make the example simple), but the problem occurs with totally different files in totally different locations also. For example, same thing happens if I compare a file from U: with a file from C:, and try to save the file from U: (where U: is network drive of that specific network, which causes the problem).
This problem does not happen with every mapped file system, but only with some of them.
