Open with -> Choose Program Notepad Opens for all file types automatically

Hi Gurus:

I am running on Desktop, Win XP Professional, SP3 Ver:5.1.2600.5512

Till yesterday this option worked fine, today only i noticed that if I

Right click on any file type (e.g. MP3, DLL), Open with -> Choose Program.. Opens Notepad automatically :confused

Does not allow me to choose a program as it used to before, I am using SP3 since two weeks now, but only today, this weird selection started happening. :banghead Is it that i am hacked??? :foolish

I did use nlite to generate an .iso for backup purposes, never used this .iso file. In this nlite I opted

Tweaks Section -> General Tab -> Explorer -> Associate additional file types with notepad (explanation - Open LST, CFG and NFO files by default).

I do not think it has any significance, but wanted to mention anything i did related to notepad association.


So any help in this regard is greatly appreciated by me and my kids and my grand kids.... :wave
