Hello Robert. I understand it, but I do not see a better solution. How to solve this problem another way? This will require very large changes in osgpartitsle .... to fix one little problem ..... and this will require a lot of time
I do not know who can help me in solving this problem. Do you think my solution at all bad? I really want to solve this problem in version 3.0 ... but not knowing how to do it ... Thank you very much for your participation in this process ...
