It's a (security) feature, not a bug!

sudo won't ask you for a time, about 15 minutes should be standard. You can adjust that to a longer value using visudo:

Defaults      env_resets,timestamp_timeout=-1

timestamp_timeout: Number of minutes that can elapse before sudo will ask for a passwd again. The default is 15. Set this to 0 to always prompt for a password. If set to a value less than 0 the user’s timestamp will never expire. This can be used to allow users to create or delete their own timestamps via sudo -v and sudo -k respectively.

If you really don't like it: log in as root (probably by setting a password first and enabling log on to X11)

Please don't...if you want to, make the sudo session last longer, I'm fine with that, but don't work as root by default and especially not with an X-Session on top of it...it's a very effective way to nuke your system in so many different ways you can't even imagine. There's a reason why it is always frowned upon in the Unix/Linux world...hell, even Microsoft realized this (a decade too late, but hey, at least they're learning). – Bobby May 11 '11 at 9:00
@Bobby: absolutely, just as I said: it's a feature ;-) – mbx May 11 '11 at 9:05
