Thanks for your reply ! And thanks a lot also for your work at squashing bugs !!! :)

In fact when building the filters I tried to manage the most directly useable presets, even for custom filters. And yes I appreciate a lot using mouse wheel for adjustement (but I don't remember if wheel adjustment worked on windows) ; that's why I asked to Jazzynico to make custom filters the most progressive possible, often using floating point. But on the other hand when I create new filters from existing one or not I would be able to enter precise numerical values. In some cases if I delicately click or double-click on numerical values that works, but not always because this area seems to be very sensitive. There aren't other problems.
