I have a decent laptop which is made of aspire 51oo on my table. While working with my laptop, very 0ften i am facing a problem with google talk and internet download manager... It is displaying me the following message for an error.... "Google talk encountered an internal error, and must now close. Ok to report this error to google?" I have uninstalled it for one time and re-installed for other. But still it is showing like this message sometimes. And i am also getting trouble with internet download manager....as it is asking me to update for newer version which not for free! What should i to get rid of these above two issues?....
