I tried the desktop (wine based) version of teamviewer5 from my 32-bit openSUSE-11.3 (athlon-2800 PC) to our ancient Fujitsu-Siemens Amilo 7400M laptop (while runing its winXP partition) running teamviewer. I noted the same problem with the mouse click (ie does not function in many cases). I’ll look into checking out yuuguu next.
