[PROBLEM FIXED]
I suppose this bug is from previous versions of Wavepad that i used. Just edit the registry file to delete it.
FIRST Backup your registry!!! IMPORTANT
Click start -> Run -> regedit
Click Find and use the keywords Edit Sound File and Batch Convert with Wavepad to find it in the registry
Delete all the entries you find!
and youre done
I installed Wavepad 4.03 and turned off the option to remove wavepad from context menus.
It kinda worked because I'm still left with two options even if the option is turned off:
Edit Sound File
Batch Convert with Wavepad
I've tried uninstalling and that removed "Batch Convert with Wavepad" but "edit sound file" is still there.
The thing is i like using Wavepad I just don't want it on the context menu. Ive seen a 2-year old thread about this but its not really useful.
Can anyone help me?
