I have been using TextPad 7 for years with no issues but I decided to upgrade to version 9 to get better UTF-16 support. Now both version 9 and version 7 are slow opening files in some cases no matter which I reinstall.
At this moment I just have Notepad as the app associated with .txt files because TextPad is so slow when I double-click on a file with TextPad as the associated app. If I right-click and choose "Open with TextPad" it opens fast. If I right-click and choose "Open with" and then TextPad it is slow. It just spins for a while. If I open a file through a shortcut on OneDrive it doesn't do anything and the file shows syncing status. I see similar behavior on c:\temp which isn't in OneDrive.
It's a bummer because I have used TextPad 7 all this time and I don't even know how to go back to it. Thanks for any ideas/help.
