Q: not able to us app,  It runs like it is open before i use it, i photo

Are you saying that iPhoto is hung and you can't  quit out of iPhoto.  Then next time that happens go to the  menu and select Force Quit.

Then select iPhoto and click on the

Now do the following: Try this:  launch iPhoto with the Option key held down and try to create a new, test library.  Import some photos, quite and restart iPhoto to see if the same problem persists. Report back with the results.

If the problem does not appear with the new library it's your current library that's the problem. In that case  make a temporary, backup copy of your library if you don't already have one (Control-click on the library and select Duplicate from the contextual menu) and  apply the two fixes below in order as needed:

Fix #1

Launch iPhoto with the Command+Option keys held down and rebuild the library.

Since only one option can be run at a time start with Option #3, followed by #4 and then #1 as needed.

Fix #2

Using iPhoto Library Manager  to Rebuild Your iPhoto Library

1 - download iPhoto Library Manager and launch.

2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.

3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.

4 - In the next  window name the new library and select the location you want it to be placed.

5 - Click on the Create button.

Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments.  However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
