I've recently invested in a Logitech G700, which runs either wirelessly or via a usb cable. The mouse is working fine, it's a sterling piece of gear.
The problem occurs when you 'hot swap' the mouse. For example, usually I have it wireless via the dongle. It works fine. Now say I want to charge it, I just attach the cable and Windows 7 has a little jitter and I hear my 'You just connected a USB device' ping. A second later I can move my mouse pointer again.
However I can't left click on any items. At first this happened in Chrome and I thought I'll close down some apps, and it looked like the cursor was locked into that app. However on further experimentation it seems that it prevents a left click on anything, even desktop icons.
I get similar behaviour if I disconnect the mouse from the cable to use wirelessly.
My SetPoint is setup to only use the 'General' profile, and I don't have any auto-switching turned on. There is a similar issue here with no solution, http://forums.logitech.com/t5/G-series-Gaming-Mice/Left-mouse-click-issues-w-G700-USB-connection-connected-amp/td-p/717234
Does anyone have any idea's or things that I could try? Currently I have to reboot my machine each time I attach or disconnect the cable from the mouse, which is hardly ideal.
