"Please wait" bug on netbeans when I open a php project/I am not able to open project with existing sources/My enter button on the keyboard not working

This bug is so annoying:
To fix it;
click on the info icon before <?php
then select html 4.0 transitional

For Failing to open project with existing sources:
this trying removing the nbproject directory in your project folder and creating a new netbeans project with those existing files.
Another possibility:
If you encounter this on Linux,confirm that you have enough permissions in the directory you are writing to .You could be not having permissions to write into the folder and thats why netbeans can not  create its folder nbproject.

You are good to go .....
