@You : "...Yes they do, same as V1 and V2 shared the same .ini file, same with V2 and V3, and so same with V3 and V4..."

Ok. I didn't know. Thanks for the info.

But the issue remains...

@You : "...otherwise use a separate section in the file to save V4 shortcuts so V3 and V4 would be independent from one another in that particular area. "

I think this could be a very easy way to solve this issue.

Thanks.
