Hi there!
I'm using HFS 2.3 Beta #247 -- I don't know if this might have happened in earlier versions, and I have not used the "save old version" option.
Just looked today at editing the .tpl included with HFS, but I used the "Change Editor..." menu item to use Notepad++ and now I cannot figure out how to once again use the built-in HTML Template Editor!
I have cleared options, I have closed HFS and checked file type association in Windows Explorer, confirmed that there is no entry for .TPL, and checked inside Notepad++ to make sure it isn't trying to associate with .tpl files... but even after clearing options, when I select "Edit..." or press F6, the .tpl file is opened in Notepad++ again.
I thought perhaps if I tried Change Editor and selected HFS.exe that it might work, but this only offers to import the .tpl as current (which makes sense, I suppose, if I were to double-click a template file and have it install.)
Can anyone help me? I simply wish to set the editor used for .tpl files back to the built-in editor.
Thanks!
