Some issues with x-keys USB - Non OS related

Hello,

For over an year since I have my x-keys, I have the following problems:

1 - I have a french layout keyboard and it really gets all mixed up (sometimes recognize, other times don't...) when I map any key with keys not sharing the same position as the English layout;

2 - Another issue is when I map for example CTRL+F1, it just fires the F1 alone.

These issues are quite restrictive on the use of my x-keys and if someone had the same problems and found a way around it, I'll take it ^^.

Already contacted IPEng but thought here someone could have the answer.

Thanking you in advance.
