Google Blogger Usability Issue

Again I am finding some problem with Blogger. This, time it is usability issue.Whenever I go to new posting I can able to use FONT, TEXT SIZE Options from the toolbar.I kept idle without blogging for three to four days. One fine day I decided to blog, suddenly I found there is no Options for FONT, TEXT SIZE in the toolbar. I was shocked and I don't know how to get back those Options. I made some R & D in SETTING but still I couldn't find out.

At last I decided to do some Googling and I got the answer that those Options are available only at Compose Tab.

Fine Ok no problem that might be a requirement, I am blogging for the past one month, whenever I go to Posting TAB and create a new post, I can find those options without changing the TAB from Edit Html to Compose i.e If you go to new post the default tab will be Compose TAB.

So how it is possible, suddenly default TAB got changed.?
