Hi,
I get exceptions in the Lookup of a TTMSFMXEdit.
To Test:
* Create New Mulyi-Device Application
* Drop a TTMSFMXEdit on the form
* Set the following properties of the TTMSFMXEdit
  * Set AutoComplete = True
  * Set FullTextSearch = True
  * Set Lookup.Enabled = True
  * Set Lookup.NumChars = 1
  * Fill Lookup.DisplayList with "dummy" data
Run the application
Focus the edit box
Type a char so the lookup list becomes visible
Select an entry with THE MOUSE (if you use arrow keys/enter it seems to be ok)
Clear the text in the edit
Type a text which isn't in the Lookup.DisplayList
At this point I get an exception
If I change Lookup.NumChars to value of 2, 
the problem doesn't seem to be present.
