I were playing with Talend 5.0, doing a couple of jobs and saved them under the default directory where Talend is installed under the workspace C:/Program Files/Talend5.0/workspace/MyProjectName.  When I start Talend using Start->Program Files and accidentally chose uninstall.  Talend did not prompt and went ahead and delete the entire folder including data under my workspace.  There are buttons Cancel, Close, and the X button but they are all blanked out.

With other software, they prompt if you want to delete your data.  I am not sure if 5.1 has any improvement on this, if not please fix it.  It sounds very dangerous to just go ahead and delete user's data.
