Thanks to Rich Birch for this tip.
Edit the K menu by right clicking and choosing ‘Menu editor’. Then find the entry
for kate, and you’ll see it says
kate –use %U
the ‘–use’ bit means use an already running session if possible, so just
delete it:
kate %U
The quick launch bar seems to ‘cache’ the programs commands so you might need
to remove the kate entry and add it again. It worked for me.
