Hello, I come back on the initial question. First of all, I'm a super-fan of virtuawin for years! I had the excel problem too and when I tried to change the windows rules, it didn't work. However, I've observed that, even if I go to "Windows rules", click on XLMAIN, click on "MODIFY", changing the "method for hiding window" to "Hide by move window",click on "Apply" and then "ok"... when I come back to windows rules, the rules of XLMAIN are still the initial one! So it seems there is a small bug in...
