Whenever I start Notepad++, it tells me that some actions are still to be taken with respect to plugins, and if I confirm this, it asks me to run gpup.exe.
No matter whether I confirm this too or not, the same repeats over and over. I have also tried to re-install Plugin Manager, but it does not help...
Delete the file called something like gpupactions.xml from your notepad++
config directory - the settings dialog in plugin manager shows you where
your config dir is.
It might be called pluginmanagergpup.xml, I can't get to a pc at the moment
It'd be good if you could send me a copy of the file before you delete it,
so I can work out what went wrong.
