Title: Lefty crash, memory access violation
Submitter: Bailey Miller

Subsys: Dotty/Lneato/Lefty
Version: 2.18
System: x86-Windows-SP2
Severity: major
Lefty crashes when using a series of widgets to create a dialog type box.

I have a sample lefty script that uses 4 widgets to create an array of a button and a text output box that are embedded in an array. For most operations the script works fine. Some specific operations will cause lefty to crash from what Windows says is, "Unhandled exception in 'lefty.exe', 0xC0000005: Access Violation."

To reproduce the error, load the below script into lefty. Left click once on the canvas to create ONE node. Then right click and select "open dialog". The memory access violation should occur, causing lefty to crash.

It would be most helpful to solve this problem, as I have a fairly large program written that uses similar lefty script functionality.

Thanks, Bailey
