"Avoid moving over unit" seems not working very well as they move over themselves.

Well I have no idea why it crashes As I said, often it crashes but not always.

But if you want I can shoot a video so that you really believe me.

EDIT 2: I would like to use Drop shadow effect instead Dropshadow object but the effect is not very editable :/

OS Version: Windows Vista

Latest OS Service Pack: SP1

CPU Name and Speed: AMD Athlon 64 X2 Dual Core Processor 5000+

RAM: 2GT

Video Card: ATI Radeon HD 3800

Video Drivers Version: 8.471.0.0 (Well it's not the newest but this version works better than the new one )

Well I don't really know. In my computer it crashes almost everytime I try that.

EDIT: It also crashed when I pressed CTRL + Z few times earlier.

EDIT 2: And btw. why it creates only one shadow to one human soldier? Why don't they all have a shadow?

Event Editor -> Start of layout -> New action -> Dropshadow -> Softer tab -> *CRASH*

Well in fact sometimes it crashes and sometimes it doesn't so close the application and try it again if it doesn't crash.
