ATI2014 and DDE messages

4 1/2 months and no answer, I guess that makes the answer no...

I am having the same problem with TextPad. It is also clearly related to ATI2014. Textpad used to have a work-around for this issue (see https://www.textpad.com/add-ons/ and look for the add-on named "DDE Messages") but it no longer works for updated versions of TextPad (I use TextPad 5.4).

Since I am not going to wait four months for no answer, here is my workaround:

Disable Textpad's Context Menu Integration

• Open TextPad
• Click Configure > Preferences
• In the General Sheet, uncheck Context Menu and click OK
• Close TextPad

Add Custom Context Menu Integration

• Open Windows Registry Editor (WinKey+R, regedit.exe)
• Navigate to HKEY_CLASSES_ROOT\*\shell
• In the shell key, create a new key named TextPad (right click > new > key)
• In the new TextPad key, create another new key named command
• Edit the string value named (Default) in the command key and type c:\program files (x86)\textpad 5\textpad.exe -q %1
• Close registry editor

Obviously, your textpad.exe might be in another location depending on your windows version, drive letter, and whether you used a custom installation path.  The one thing that this will do differently than the shell extension that comes with TextPad is that this will always open new files in a new instance of TextPad.  The shell extension opens anything using the TextPad context menu handler in the same instance (different tabs).  Hopefully this will help out someone other than me.  A 30-second explorer hand every time I try to use my text editor is not acceptable.
