I've been using Synergy for a while at work to connect my XP machine (the host) to my Win 7 laptop (the client). I previously was having issues with using Synergy and the UAC prompt, as described in this question, and have had no issues since, until recently.
I upgraded to Synergy 1.4.10 and now am seeing odd behavior whenever a UAC prompt appears on my laptop.
When the UAC prompt appears on my laptop, Synergy momentarily drops its connection to my laptop, causing my mouse and keyboard focus to revert to my host machine (the XP machine). After about a second or so, though, the connection gets re-established and I am able to type and use the mouse buttons in the UAC prompt. Once the prompt clears, the connection drops again for a second, and then gets re-established again.
Is this something to do with configuration or perhaps should I just chalk it up to a change in behavior in version 1.4.10?
EDIT: Updated to 1.4.11. Still the same issue. Now it's with a Windows 8 Pro 64-bit client and a CentOS 6.4 server.
