I've experienced a strange behaviour during drawing in MapInfo. Snap function doesn't work. Pressing the S key has no effect. I can't turn off snap. When I start drawing in snap mode, the program freezes. Any ideas what the reason is?
Some years back I saw a client with some seriously bad performance with snap enabled. It turned out their data was on a network drive, they had a poor network connection and finally, they have 50-70 layers all selectable.
A few hints:
- try to only make one layer selectable, the one you want to snap to. You can right-click the layer and use Make all other layers not selectable. Or at least limit the number of selectable layers if you have a lot of layers.
- try to use the Snap options from the Nodes dropdown on the SPATIAL tab
