hide edge tab freezes whole system

[curious]

I am on a mac computer working with debut 6. Everything works fine until i want to hide an edge, and i can hide about three but on that forth click it freezes the system and when it comes back it takes about a minute to perform any task. Simple ones from moving an item to drawing a box. Anyone else have this problem and know how to fix it?

Have you upgraded to 6.2 yet? when I updated mine to 6.2 a lot of issues went away.
