Good news... problem finally solved

Good news for all bloggers who have been experiencing problems with missing editing icons in the new post page.

It has nothing to do with Blogger and nothing to do with internet browsers (both IE and FF didn't work for me). It is actually Singnet's problem. It seems to affect singnet users only I think.

Here's a solution from the forum for those using Internet Explorer.

Tools -> Internet Options
Click on "Connections" page tab
Click on "LAN Settings" button (if you are using Broadband)
Check "Use a proxy server for your LAN ..." checkbox
Click on "Advanced" button
Under HTTP type, input "proxy.singnet.com.sg" for proxy address and "8080" for port

It works for me!
