window os parameter is incorrect

[OnlookerRian]

When using MultiClientGetID(), I got a return value of -1.

After checking, I discovered that the problem was caused by the "—" character (which ends up being interpreted as "c-window-number").

Replacing it with "-" fixed the issue; however, since the function expects "mc-window-number" as its input, removing the "-" altogether resolved the problem correctly.
