Android project loading to phone removes previously installed project

I am working with Eclipse and running my apps o开发者_开发问答n my phone(Motorola DROID2 GLOBAL, Android 2.2). Once I install a new project the previous one will disappear. Any ideas? Is this Eclipse problem or the phone?

Is a normal behavior of the Android development enviroment, it remove the application that you're debugging to upload the new one (new version). It is like when you update an application with the Market, the old one will dissapear.

The problem was related to the operating system. Once I got upgrade pushed on my phone I stopped having this issue. Now it's all works just fine and can see all my apps available.
