Textpad - Open new files in same instance by default
I've been a TextPad user for years, and when you install it, it adds an item to the context menu in explorer called "TextPad" that will open any file with textpad, regardless of the extension (whether or not its readable is another matter of course). Now, I could be remembering wrong, but I recall on older computers, if you opened a file with this method, it would open any such files in the already-running instance of TextPad. Now, when I do this, it seems to open a new copy of TextPad every time I open a new file. I'd perfer it to use the same instance. How can I enable this behavior?
