I've come across some issues with the program, although it's still amazing and these issues are easy to work with.

I consistently see, after a long period of use, Plexer start sending some windows duplicate keystrokes. So I type in for everyone to do "/use hearthstone", and one of them will do "///uuussseee hhheeeaaarrrttthhhssstttooonnnee" instead. I close the program and reopen it. I'm just concerned that this will look like something illegal if someone from Blizzard ever saw it, besides the minor annoyance of restarting the program. It's not that big of a deal for actual playing at least.
