Thank you, Guys for your answers. I can see clearly that Serif policies are odd, as they completely ignore some customers and their needs and care only for their business. Unacceptable to me. This time they decided not to support customers who use windows 7. They completely ignore Android (which is the most popular OS in the world (more popular than Windows, generally). They do not support Linux, others companies do. What will they decide tomorrow? Subscriptions? Who knows? But I am afraid, they will dissatisfy us more than once...Therefore I cannot count on them. I will choose GIMP+KRITA+INKSCAPE+SCRIBUS+DARKTABLE+NATRON+RAWTHERAPEE to have peace of mind. Supporting these projects will be well money spent that won't turn against me. I will occasionally buy some other apps that support Linux (or at least work on WINE or Cross Over Linux)
