Most recently Gmail made a change to the compose new email feature. The thing is, they made this change last October but it was in Beta unti now, when they have made this the new default. But what people seem to lose sight of is the fact that with changes, there are always settings to switch things to your liking, as with the new compose, you can choose to 'temporarily switch back'. But before you do, think about why you might be doing this and realize that the new methods only make things more organized, allowing you to actually compose more then one email at a time, should that be one of your pre-requisites or not. More importantly, you should take advantage of the gmail themes and other settings that you can configure to your own liking.
As always, any issues you may have that you simply can not figure out on your own, you can contact me directly and I can try to make things a little more understandable and clear.
[UPDATE]
It seems people are still having 'issues' with the new gmail compose feature, even though it was released in Beta last October, many choose not to give it a try and are now faced with the new way is the only way... well you can learn more about this new way here. Also, you can click within the drop down menu of the new compose window and choose to revert back to the old way, although you will never hear that from me! There is always a method to go back to the 'classic' method of things, but that doesn't mean you should. The reason for this initial blog entry was to express how important I feel it is to allow for change in the first place!
