Bug, keyboard commands mixed.

[Avel 0]

I use 1.7.3 basic version of Synergy. Server is Win 7, client is Win 8. For awhile software works fine, but then at some point it will start mixing my keyboard commands. I can't write some letters, and while I push like letter "t" it might minimize some game or something else really weird. Sometimes it mixex keyboard like when I push letter "1" my computer opens google chrome, and when I push letter "2" computer opens some game etc. It's like I can't even use ctrl + shift + esc to open task manager. I have to restart computers to get synergy working fine again. I tried repair option and everything already. Does anyone have any clue how to fix this issue? I can't really even use synergy at the moment because of this.
