Under Config Field Settings
Any field that requires a text field change its type to text (Large)
If the field type requires a file menu i change it to file
If a field requires a drop down menu I change the type to drop down menu
If the field requires a textbox or HTML Editor type i change it to HTML type
The system crashes regardless if i change the field types or not, It randomly crashes normally when you try to define features, I get 2 forms in there then crash. Doesn't matter the order of the forms i try to create.
After another 4 hours of experimenting it seems to have a great deal to do with the amount of fields there are in the table. Smaller tables crash a lot less than the larger ones but it still takes me 3-4 attempts to get one set of pages complete. Restarting DW, clearing the cache and shutting down all property windows in the process.
Hope this helps, I can do a screencast for you if that helps as I can get it to crash every time.
