i cannot map any combination involving the Win Key also known as Mod4 in certain WMs. it's apparently named as Super_R or Super_L in xfce4.

i can only use the key alone. i wanted to have xfrun4 mapped as Win+R, but i cannot seem to be able to do it. combinations are not detected.

my xorg.conf keyboard settings : 



Reproducible: Always

Steps to Reproduce:
1. try to assign Super_L/R + some key to any command/action.
2. 
3.

Actual Results:  
when i try pressing Super_L/R+some key i get only one of the two - the one i released later.

e.g. when i try to press Super_R/L + a

- when i release "a" first i get Super_L or Super_R as a result accordingly.
- when i release Super_R/L first i get "a" as a result. 

Expected Results:  
proper recognition of key combinations.
