An issue occurs in Claris Draw for Windows in certain cases, when you group objects then choose Transform.. Rotate 90 degrees, under the Arrange Menu.
Issue: The objects seem to disappear, however, they are still there, on another part of the page.
Workaround:
1. Choose Show Object Info, under the View menu.
2. Select & Group your objects.
3. Select Transform... Rotate 90 degrees, under the Arrange menu
4. If the object seems to disappear, look at the Show Object Info box. One of the numbers may show a negative number. Change that to a positive number and your Rotated and Grouped object will reappear.
Lastly, Ungroup the objects, rotate them and then regroup them.
