I can't get consistent close tab action with a browser window except with XP. Trying to run ubuntu 10.4. - 64 bit
If I pull down the menu and select close tab, it works. A cntrl-W will work once after that. Sometimes it will work for a while.
Hrmm, well you do not say what browser you are using.
I have no idea what Ubuntu uses these days, since I can't stand the rotten thing, however why don't you install Firefox, that is the only browser I use in either Windows or Linux, and last time I used tried in Linux CTRL+W worked just fine.
