"Use Startup File" in preferences not working

I’m trying to have TD open a file when the app launches. I’m trying to use the preference “Use Startup File”
When I open the dialog and select a .toe for some reason it’s putting two paths as the variable. The first path is the desktop path followed by the path to my .toe C:/Users/user/Desktop/D:Projects/etc/etc/file.toe
This also happens when the toe is on the same drive.
Then after selecting apply and accept. If I view the preferences again the 'Use startup file" variable is set to $startfile. And when I close and reopen TouchDesigner it doesn’t open up the .toe It opens up an empty start file NewProject1.toe

oddly enough if I put my .toe file on the desktop and then choose it as my ‘Start File’ the varaible works correctly and shows my .toe. However restarting TD it doesn’t open my file, instead it open NewProject1 again

Thanks for the report. We are looking into it.
