I just downloaded V1R5.1. I am still having the problem of DS crashing when trying to use blocks. some times it will crash when I select "insert/ Block" from the drop down menu. Other times it will wait until I select the block I want to insert. 

I am using the default file locations for all files. 

Has anybody found a way to make V1R5 work with windows?

This has been a problem since V1R5.0, but not in V1R4.
