I checked this program and were not able to reproduce any such bug.

I can tell you two things which may remove this problem:
First, restore the system to its factory settings. (you might not be willing to do this as you have to backup all your data which might be a long process depending upon your storage). This should definitely eliminate this problem. ;
Second, you can create new user account with administrator privileges. see if this eliminates the problem. If this works, you can copy all user folders content (old one) in new account and delete old user profile.

I am glad that your application is working fine now. You do not necessarily need to remove that profile. It will not harm you anyway except occupying few MB's of space in your hard drive.
For Itunes, try this: http://hubpages.com/hub/move-iTunes-songs [just consider your new profile as a new computer]
For Firefox: http://kb.mozillazine.org/Profile_backup [see Manually back up the profile]
For desktop etc, I guess you can redo it again..and it will be fun...:))
