Thanks for the replies guys. It seems that Rob72's suggestion about the placement of FBlit was a good idea. In my setup it was placed according to the guide, however once I've put all 3 after Resident Assign REMOVE, the system seems to run fine now. :-)
Seems like the best place to put it, at the end of the SS file, so that other stuff doesn't get corrupted.
Once again, thanks to all replies, and especially Che's...I mean Rob72's! ;-)
