Whenever I drag my cursor over the 'effects' option from the menu, there is an extremely long wait time before the window actually opens. The wait is sometimes 15-25 seconds, and is longer as more work is completed. I have tried uninstalling and re-installing Paint.net, plus the same with the various plug ins I have. I have the same plug ins on other computers and none of them do this. It started recently and I do not know why. Someone help, please.
