A. Reboot after install; USBs added 1 at a time. Win7 & UM monitor numbers are different.
B. After Restart without disconnecting USB adapters.
Different numbers. UM Smart Taskbar did not show up on one monitor (Win7-#5 UM-#7).
C. Shutdown, Disconnected USBs, Start
Plugged in USB #4 before USB #3. Different monitor numbers.
D. Shutdown, Disconnected USBs, Start
USBs connected #1 to #5 sequential. Same as A.
Conclusion (For Now)
Shut the computer off then unplug the USBs. Start computer & log on. When fully up connect USBs sequentially #1 - #5. Hopefully the UM numbers will stay the same so profiles will work.
(1-1-10 Shutdown, Unplug USBs, Startup, Plug in USBs one at a time in order, has worked several times. The monitor numbers are as expected, though Win7 and UM monitor #s differ.)
