The first problem I have discovered after upgrading to Windows 7 (32 bit Ultimate ) is with the simplest of software’s – Google Talk. Google Talk has crashed 4-5 times in last few days and I have reinstalled it three times, finally dumping the stable version of Google Talk and installing the Google Talk Labs Edition.Ever since I upgraded to Windows 7, I found the typing in Google Talk was very slow, ie the program was not responding as slick as it should.
When I tried to Google for any possible solutions, I found more complaints than answers many users have mentioned Google Talk either slowing down or crashing. Some users have tried running the program in compatibility mode of Windows XP SP3 or Windows VISTA SP2, I tried both options but unsuccessful in both attempts.
One more problem I noticed is whenever the Google Talk was opened in Gmail window, it would crash the Adobe Shockwave player (220.127.116.111). I believe Google is responsible for both these problems.
So expect a newer version of Google Talk for Windows 7 and for time being try the Google Talk Labs Edition.
