I still have problems with getting the target panel content while a backround/queue copy operation is in progress. Turning on the option EXE/LNK not on net helped a little but even with this option the browsing in target panel is almost impossible. I've tested WiFi (802.11n) and wired 1Gb connection. I've copied some files from Dell Latitude E6510 to my PC via Asus RT-N56U(WiFi) or 3Com switch (1Gb). Window 7 64 Ultimate on both PC. I use UNC paths, the .INI was default during tests.
1Gb (EXE not on net ON) - usable, but still slow
1Gb (EXE not on net OFF) - very unresponsive
WiFi (EXE not on net ON) - very unresponsive
WiFi (EXE not on net OFF) - unusable
Is there anything what can I do to improve browsing in the net target panel during backgroung/queue operations? Now I am not able to take advantages of these operations in network environment

Thank you
Tomas
EDIT: I have network autotuning off because of stability.
