I had this happen to me once and I am not sure that this is your problem,
but here goes...

I was growing NIH3T3 cells and plated them in 100mm dishes.  The next day
I went to look at them and they were in monolayer, but sliding in sheets
on the dish.  I found out that I had plated on non-treated petri dishes in
stead of tissue culture dishes.  

Could that be it??

I doubt it, but anyway...
