Thanks for the reply Mouser.
Yes. Apparently, I enabled that setting months back & the app is restarted along with system restart many times.
I notice a peculiar behavior. If I activate the app through a shortcut, and then try Alt+Tab, it shows up in the alt-tab window. I switch another window now & again try alt-tab, FARR is still there in alt-tab window & now switch back to FARR. So this accounts for two swaps of FARR & the other window. The issue is after this. FARR will not come back on alt-tab window till the time it is there in taskbar.
If I close FARR window & activate it again using the shortcut, it will again appear on alt-tab window again for two swaps only. Isnt it strange?
Plz see if this can be resolved. As I said, I am not sure if it is because of my Win 7 64 bit. Can you confirm on this?
