Refer to the above screenshot, frequently the "ok" button and "cancel" button are outside of window and become inaccessible in Simulate. I have to close Simulate and restart it again. Is there any better way to access the "ok" button?
P.S. BTW, in Simulate, the popup windows for selections (for example in assigning Rigid Links, Weighted Links, etc) are TOO small and can't not be dragged wide. Is there any better way to make the selection window wider?
