Hello,

I had the same issue on Xp SP3, with .php, .inc files where Pspad starts when
double-clicking on these files but without displaying content in it with last
version of Pspad (it was ok with old versions!!). Here is how I corrected that
beneath some googling about "c:\Program Files\PSPad editor\PSPad.exe" "%1" . I
found that we must not only register the Pspad program as default to Open and
Edit the target file (add the "%1" suffix in the
HKEY_CLASSES_ROOT\phpfile\Shell\Open\Command and Edit command), but for some
file extensions (.php is concerned!), in HKEY_CLASSES_ROOT\ group, we must also
add the "%1" suffix in the HKEY_CLASSES_ROOT\php_auto_file group for Open and
Edit commands. Not all file extensions have these auto_file group!

I presume everybody knows how to edit a key by selecting "Run" then type regedit
then click "OK", then select HKEY_CLASSES_ROOT and expand it, or just select
Edit/find... menu and look for pspad keys, then press F3 until you find the
php_auto_file group.
Do the same for other extensions you like.
