I am working with QCAD 126.96.36.199.
Sometimes i cannot fill with hatches, especially after i have worked on objects, which should be hachured, in more detail. In order to fill them with visible hatches, i have redesigned them totally.
In order to test this, i vave created simple objects, like rectangles, and filled them immediately after creation with hatches. This works.
In addition, also solid filling didn't work.
I have detected these problem in Win Vista as well in OPENSUSE 11.4.
