Strange Blip Problem

For the last couple of days when I've gone to add a new entry, I get the choose photo screen, click on that and then a little explorer window opens and my computer freezes.

I have to switch off and start again.  When I open Blip again, everything works fine.

That's the sort of thing that drives me scatty.

it certainly is the sort of thing that drives all my other thoughts about today completely out of my head and all I'm left with is "Blip fudged up again".
