Mask: Subtract with brush not possible
I can't subract from a mask using the brush (no difference between different types of masks). However I can add to a mask using the brush.
Also the other tools (e.g. linear, radial filter, etc.) to add and subract from masks are working fine.
At the beginning of the week I could subtract from a mask using the brush so I not want to exclude that I hit a setting which disable this function.
I also synchronized the photos with my iPad an there I colud subtract via the brush.
Any ideas how to fix the problem? At the moment I try to avoid a reinstall.
