Debugger Error:scope stack underflow

BlitzMax Forums/BlitzMax Programming/Debugger Error:scope stack underflow

Hi there.

Cann anybody tell me what this means?

"Debugger Error:scope stack underflow"

Can you post some demo code that reproduces this?

This only happens while I use a DLL called "grFinger". I use this to implement a fingerprint scanner in my Project. You cant use it without such a device.

I can mail you the sources of my project if you want.

It happens often when a callback function crashes.

(callback function crashes and the error is catched)
ERROR: GrImageEventCallback: Unhandled Memory Exception Error
(another callback event happens)
GrFingerEvent:GR_FINGER_UP
(application freezes)
